the falling and the warm feelings are pretty usual with bud, and phychedelics dont really do that much.

however, if you like colours and patterns and stuff, psychedelics may be worth looking into a bit. check Erowid on information about "salvia divinorum" and magic mushrooms (usually cubensis)

quick explanations:

salvia: about a 1-5 minute decent to massive hallucination (deps on dose), followed by about 20minutes of a stoned feeling.

shrooms: lots of vibrant colours, shapes, and everything has a habit of shiftint/swirling. lasts 5-10 hours and is very dose dependant as well.
