Although I have not done stuff like that, I find that I having really lucid dreams is also a great experience and can open your mind.

Specifically, if I want to have a really lucid crazy kind of dream I just eat a lot of spicy food before I go to bed. The chemical reactions in your stomach affect your brain and for most people if you eat something before you go to bed you will have more vivid and interesting dreams. I have found that when I do this I can actually control what happens in the dream(like I am aware it is a dream type thing). I read somewhere about the hot sauce and spicy factor that it makes it more intense.

The vast majority of the time I do this I remember the dreams after waking up and can still recall the dreams weeks and years later(almost like I actually experienced the dream in real life).

It is pretty neat and you should try it sometime!

One of the re-occurring dreams I have from doing this is that I am backwards in time working at a retail store(a previous job I had when I was younger). Only the problem is that I don't have any pants to wear to work for some reason, in this dreamworld you have to show up to work or you will get in HUGE trouble. So I have to go to work with no pants on. I help customers normally and it is quite busy. Some customers don't even notice I am not wearing pants too, and just interact with me likes its normal. I show them where products are and explain the products and do normal things. But then the dream gets crazier as time goes on.

It starts going to also not having a shirt on or no shoes. Then some customers get mad at me and call me lazy for not wearing clothes and stuff like that. I ask the boss if I can go home and they tell me something absurd like "you should have been more responsible and we are busy so you can't go home to get clothes." That particular dream usually ends with having too many customers to wait on and eventually I am almost naked(but not exposed in for those parts). I then cannot wait on all the customers and just quit the job in frustration, usually at that point I wake up and have to use the toilet in real life.
