to hallucinate means to see/hear/etc. something that is not here (outside of your mind)
i don't consider that psychedelics make me hallucinate at all
they make me conscious of things that are here but that i usually don't notice
some people interpret those things as halucinations, but if you ask a little bit, you'll probably find flaws in their interpretation of what they became conscious of
ex : you don't see the floor waving. the image of the floor that you get is waving because it is not interpretated by your senses in their regular state
if your senses were tunes other wise, maybe you would always see the floor waving and you would see it idle when on psychedelics
there's no true or false, just different interpretations
the floor being made of 99.9999999999% of emptiness and of paticles moving at high speed, the idea that the full, unmoving floor is the real thing is for instance totally unjustified
