Something I'm surprised hasn't come up yet is the ability to flex... "something" in your brain and turn hallucinations on and off.
I grew up in a Buddhist family and was meditating since an early age. I'm not sure if this was related at all but since I was young I could look at things when I was bored and do something in my brain that would cause the patterns to move. If I then needed to concentrate I could focus and it would go away.
I did some research and found out that there is a common effect with meditators that they can meditate while on drugs in order to mitigate or in some cases even deactivate some of the effects. So if you want to experiment it might be good to learn a bit so you have an extra tool to work with your mind while you're altering it.

YMMV of course.
