more ideas:
-try to add really long lists of numbers or do complex math and see if you get the result right. I think Laberge or someone did something like this involving predicting what day your birthday will fall on in X years.
You can use whatever props you need. So if you were to do your computations by putting rocks on the ground to keep track, or perhaps scratching lines into the table, maybe you could do complex calcualtions. for example, you could draw a line graph in the sand (of the calendar) and cound the days for each month, then add them up.
-Try to make a DC who is actually YOU, an exact copy of yourself, and see what they say. You might even try to take control of them and control both. Or find a mirror. Mirrors seem to be scarce in LD’s, i wonder if it will behave realistically.
-See how much pain you can make yourself feel. I know this sounds sadistic, but ive always suspected that LD’s are biased toward allowing you pleasurable experiences, but that the brain is weaker at simulating pain.
So try cutting yourself of sticking your hand in a hot flame, and see how much you can make it hurt. It would be interesting if the brain could make it hurt so much you had to stop. THat would be awesome IMHO.
-see if you can conjure emotions on tap. Instantly be overcome with sadness, happiness, rage, fear, etc. (if just willing it doesnt work, maybe you could still orchestrate situations that make you feel emotions, such as fear.)

Regarding the 4D vision, could someone explain how exactly you would see in 4 dimensions simultaneiously?
Would you achieve this by mapping a set of points into space in the X,Y,Z cartesian dimensions… and then adding a fourth dimension W - and cross reference all 4 dimensions with eachother and make each perpendicular to each previous dimension… (and make sure your points have values in all 4 dimensions - not just XYZ coordinates but also W coordinates.)
and then you could somehow somehow SEE all four dimensions as a coherent simultaneous relationship?
this would be in contrast to the fact that we can only see in 3d now: we could either see XYZ, XYW, YZW, or WZX one time. (even though any point in any graph also has a fourth value for the fourth dimension which is not shown in each of those individual graphs. the complete picture can only be seen by looking at all of them, but you cant see them all at once.) Each 3d graph would be unique but would share a plane with every other. All the points on each of those 3d graphs would, when added together, equal a four dimensional picture. We cant see all four at the same time (XYZW), because where would the fourth axis go?
but i guess its possible… but am i even visualizing the concept of 4d correctly?
