In physics, the 4th dimension is considered to be time. In mathematics the 4th dimension is just like isotope777 described.
You cannot see 4th dimension/time in a dream. This would enable you to predict the future. But since you have total control over your dream you can always change events so that your prediction would be wrong, etc…
Why couldn’t you see the 4th dimension/time in a dream? It’s a dream, and the only future you would see is the dream’s future.
It’s possible to do anything in a dream… it’s a dream. It’s only when it gets to your dream interacting with the outside world (i.e. shared dreaming, OBE, etc…) that it becomes questionable.
i always tohught 4d is time traveling…last night i was lucid and i was sitting by the window with my guide near me and i saw things changing very fast, and i thought it was like…time moving or something
You can’t see time in a dream because that would mean that you could see a “fate”. In lucid dreams there is no fate. You could always just say, “well, I’m not going to let that happen” and run around instead of flying, for example. Because you have total control in your dream, there can’t be any fate to look into.
Of course, seeing backwards in time is OK - you’ve already done whatever it was!
i think it is possible to see the “4d” in a dream. yes you would see the furture, just not the future of your dream. you would the future in the real.
i am referring this thing i read:
"Precognitive Lucid Dreams
When you have some successful experience with Shared Lucid Dreaming you can give Precognitive Lucid Dreams a try. Intent is also an important key to have Precognitive Lucid Dreams. When you lie in bed trying to fall asleep you need to program this intent to have a Precognitive Dream, and when your Dream starts do have you to recall that intent. You should give yourself appropriate affirmations while you are waiting for the hypnagogic imagery to start. When the dream starts you do need to check your level of consciousness. Do all the tests and make sure your logical mind is working. The next thing you need to do is fully focus on your intent. Make it perfectly clear, shut your eyes, shut down all signals from the dream and let go. Move into the field by intuitively driving yourself with the desire to go there. Let go and feel yourself moving towards your desired source. Let time and space go, just flow with your intention. You may feel a melt down for a second until before you arrive there. Wherever you are in time or space will happen later in the physical world. Just observe whatever happens and enjoy it. Remember to write it down when you wake up, for later verification."
dont know if ths is possible though… w/e 
Here are some cool stuff 
1:Fly to the end of the universe
2:Transform into the sun
3:Fly in the speed of light and see what it looks like
4:taste something you never tasted before and then taste it for real…( i am sure sombeody did this)
5:and one last thing, Ask for me and see what I look like,when sombody found me I`ll post a picture and se if I looked anything like in the dream,
Have some fun guys, fun for me anyway would consist of some serious DBZ wars hahahaha. Or something like…be the main spectacle at a huge concert like WOODSTOCK.
Well., what IS lucid dreming anyways… isnt it just our mind giving our body sensations? sensations that we choose to have
we can even feel the sensations of experiences that we never experienced in real life… such as flying, we all fly in lucid dreams, but no one of us has ever flown in real life, yet we know how it feels – that…, ( IMO ) is one of the best benifits of LD ing,… feeling sensations that we cant, in real life
i suggest that trying to experience sensations that you could Never feel in real life, would be the best thing for all of you who can lucid dream at will,
unique sensations such as., turning into a small plant, and then Feeling the Sun give you energy, i imagine that that must be a really unique feeling,… by being able to be energized Not by putting material substances in our bodies, but directly from the sun,… i could be wrong, but it seems like it will be an amazing experience,…
another unique experience would be to change yourself into just an engergy ball., and feel your own energy around you, and be able to move around without walking
it would be cool if anyone does this, and post it describing how it feels like.,and if you suggest doing this in an LD,
Come back Ureon!!1 
hey…got another idea.
to help with remainig lucid or to do something while your lucid. create a magic lamp (a la aladdin) and rub it to make a genie appear. then make it grant your lucid wishes for you. just a thought.
thats a great idea
Let’s not get carried away here. Lucid dreams can only emulate the senses you possess in your usual waking form. What’s all this talk about viewing the 4th dimension, or becoming an entire planet? How could you have experienced anything in real life that could have taught you what this would be like?
Vision is 2D in real life, and 2D in a dream. It’s a hardware limitation, and the same hardware is used when dreaming. 
I thought it was 3D??
The 3D part is just an illusion because we have 2 eyes at a small distance from each other, causing the images to merge, allowing us to get some idea how far away objects are. Disregarding this, we’re still only seeing a 2D ‘picture’ of the world. Objects are hidden behind other objects, etc. Our eyes work the same was as a traditional camera, which takes a static image of the world mapping only 2 dimensions.
Anyway, the point is that we simply couldn’t even simulate viewing the world in 3 or 4 dimensions, and our attempts to do so would be purely an imaginative mixture of 2D equivalents constantly flickering between several different angles in accordance with the mind’s inability to concentrate on multiple items simultaneously.
Hey Raven24
Yea, I met two Ravens, I looked for them and found them sitting in a tree.
I haven’t posted about it because I don’t remember exactly what they said but I can try and retell you what I remember.
Raven 1 (looking at me then other raven: You want to know what us Ravens have to say about the world?
Raven2: We are a lot more physical in the real world (this one seems to be smug and slightly mocking.
Me: I was told to ask you.
Raven 1: You have to think ahead.
Raven 2: Are you sure we are what you are looking for?
…
I don’t remember anything else clearly anough so I can know I retell it to you without some form of ‘filling in’.
I will try and meet them again.
I’m sorry guys for not updating for a while (sorry blazin >D).
For some reason, since I started this project, my recall has been worse!
I don’t want to post my experiences untill I remember them clearly, I do have flashes of eating something as a lion but they are only visual and I don’t want to ‘fake’ it. It would be easy to let one’s imagination go wild but that wouldn’t be fair to you guys, I’m going to give 100% honest descriptions.
Maybe it’s the stress, but I simply don’t remember much since last post, and not a single entire dream to post in the diary.
Anyway, I will post hereunder what I DID do since last time, also what I already have done.
<>HatedOne, thanks for the tips, I think they help me a lot in one of my LDs where I used Green Lantern’s ring (DC comic book Super Hero), I will write it in the diary, it was truuuly an awesome on, I’m very glad I remember it.
<>Odd2k I do that reloading part actually (in some form or another) and it usually helps a little, but Sometimes the gun looses its form if you focus too much. Its all about flow control >D.
<>Isotope, predictability, I experiment with this a lot and I have a theory about it. You know how you never actually act and ‘are’ they way you want. Well your subconscious is the boss of you basically, LDs give you a little more control but its rare to predict what the sub will throw at you. I’ve actually been in fights with what I think is my sub (I call him Blue, I guess I should account for all this in my Diary).
Dude, I’m not going to do math in my LDs, I’m not your guy for those kinds of things.
I have flashes of meeting myself, don’t really recall, so I should try it again.
I was fighting this other guys in an LD once and they threw a squid like thing at me, for some reason it stuck on me and hurt like hell. It was really frustrating (I never loose an LD battle) and it hurt so much I couldn’t concentrate enough to change it. I eventually overcame it, used my sub’s idea of these ‘squids’, and threw them at my enemies. Man… they screamed.
<> I don’t know if you’ll believe me, but my greatest ever feeling of love was for a DC, she was wonderful. I felt extreme angst all that day, since I didn’t know that it would magically pass I was really frightened. But it did pass, and similar experiences have as well. Seems the sub guards itself from falling in love with someone who doesn’t exist… Anyways, I’m not keen on trying this too much, aftereffects are unbearable.
<>Tbab, I don’t really have to energy to put into this
<>Tasting in dream then rl, I think you only think you knew what it would taste like but you really only filled in what you thought you knew when you really tasted and knew … he he he
<>RinBin, space, seems I haven’t explored space much, I need to try this together with becoming a planet, tnx for the tip
flying at the speed of light has don many things for me. Vision wise everything goes blurry then you can basically see nothing then it is as if you’re not moving at all. It’s a good way to change dream scenery. In any case, very high speeds makes you unable to really perceive the world, and if you change this it seems you are just moving slow again (though DCs etc seem to be stopped in time).
Note to self, people to Identify in dreams, through dream guides or otherwise, Jack, Blazin and RinBin.
<>DBZ, man… DBZ action is awesome in LDs, when you go super sayajin(and I suppose have watched the show on morning tv all your childhood (in france)) you can really wreck some havock on your surroundings. Putting your hand through concret feels like moving it through dust. I should make a dream diary entry on this too.
<>Spirit, becoming a plant and getting energy from the sun is a great idea, imagine what the mind will do with that, I will definitely try.
Concerning energy, I’ve been that in many forms, I’ve been many variants of light, fire, sludge. Often I stay in some sort of humanoid form though and I have seldom placed much emphasis on it (i.e. I’m mostly using it to kick ass).
<>Magic lamp sounds like a neat Idea, maybe I’ll summon Jack’s DreamGuide with it >D
Ok, I will try to be more regular and have some better recall.
Oh my god! Have I ever before had so many spelling errors?!?!?!
Sorry guys, I swear I spell better, must be tired. You’ll just have to make the best of it.
re Atheist, what you feel in a dream is how your mind (inc subconcious) would expect it to feel. Transforming into a planet doesn’t mean that your sensations are really like they would be were you a sentient planet, but like your mind thinks it would feel like. You can’t possibly get better than that. Same goes for meditation when you change your size to encompass the universe.
I Came up with more cool thingd to do
1: Dive in to the deepest ocean (marinea deep?)
2: Astral project twice?
