Yeah, I get that. Like falling through your bed. It always wakes me up.
evryone gets that and i find it really cool and love it when it happens. for me im kindof conciously jerking myself out of fear of falling and a little while ago i was going to try to just leave it and see what happenes but i havent had on of them since , eh , ohwell
I once posted an alternative theory about these myoclonic jerks. It’s a Hindu one and according to this version, the falling sensation is the result of falling into the gap between waking and sleeping. You can master it to experience it consciously, to even control it consciously so you can keep yourself falling. Apparently there’s no fear to wake up prematurely because you’re not asleep nor awake. You’re right in the middle, apparently a doorway to deeper experiences. Here’s the topic: https://community.ld4all.com/t/falling-between-two-worlds/6570
When I get that feeling it always feels like something is snapping at my face quickly causing me to startle, something like a branch.
these things are soo fun…ive actually fallen off of my bed from this before
lol 
yea those really have been making WILD difficult for me…annoying
It is a very irritating feeling, I hate it too. It always reminds me of coming down a flight of stairs and missing one, ugh!
I experienced this a while back… in the middle of Organic Chemistry class. The lecture was as intriguing as ever, and I started falling asleep. Suddenly I was falling and jerked awake. But as I jerked upright, I also yelled, at which point the whole class turned to look at me. 
This happens to me often. Usually I’ll be in a haptic dream and I’ll trip and fall, and be ‘jerked’ awake just before I hit the ground.
I hate those. Only thing is, i wake up and still feel like i’m falling. THERES NO ESCAPE!!!
I get that quite a lot during the beginning of the night, suddenly jolting awake the moment i’ve fallen asleep, not nice if you’re having trouble sleeping 
It seems to happen more when i lay on my back or if i’ve been feeling extra tense. The only times I experience the falling sensation is upon waking after a full nights sleep.
try consciously breathing in and out in this state and when you breathe out, counting until its time to inhale again.
in the right conditions somewhere when you are counting it will go from a normal thinking voice to a hallucinatory voice, and…
if you’re lucky or talented you can hold on to the sleep state consciously.
i’ve only really experienced this once, but i also haven’t tried to very often, you have to be fairly alert yet oscillating in and out of sleep. so it’s not a great idea at bed-time.
on the inhale you want to be not thinking at all, and on the exhale you want to be falling asleep, you want to create a balance of inhale = awareness, exhale = drifting off while counting.
at least for the way i did it.
Happens the most in the middle of class for me. My classmates sure do get a kick out of it! 
When it happens to me, I see a fence, I run up to it, I try to jump over it, and my foot gets stuck. Every time. That’s what the falling is for me. But if I fall in a full dream, I almost always become lucid.
Ooh I love that feeling lol, I get it almost every time I fall asleep in class. I don’t know why everyone seems to dislike it, I think it’s a cool feeling! Usually I just “go with the flow”, try to relax even more and not jerk out of it.

I also get it in class. I think it happens more if you’re sleeping in unusual conditions or when you are too tired or at strange hours.
I generally dream about falling just before it happens, and it usually happens before I actaully get into a dream. It’s more like HI. It used to happen to me when I was little and slept with my grandparents. I would jerk suddenly and obviously my disease-obsessed grannie would think that something’s wrong with me.
I love the falling feeling–I just hate when it stops.
Sorry if this wasn’t too productive–I was just trying to ‘up’ my posts…
I often get that feeling as well if I’ve been in the water. 
Another one I get is if I’ve been riding my bike a lot all day, when I get that feeling it feels like my legs are turning on the pedals. 
Ugh, I get the same thing. 
For me it feels sort of like a cat-scratch, and for some reason it’s usually over my left eye and cheek. 
Wow, I get this everytime I sleep, I usaly feel like falling through the universe, and then I usaly think about something, like a projectile coming towards me, and I “jump” up from the bed, and then I usaly get a rush of adrenaline. Is it possible to use this to gain lucidity?
I don’t often get those anymore but they were fun!!! Also I read that the jerks that make you wake up from that sort of half-sleep are yiour brain misinterpreting you falling asleep with you dying so it tries to “keep you alive”.
Also I seem to recall that I always felt like falling when I was about to get asleep so If you can catch yourself before one of those jerks, you can probably use that to get an LD.
