an actual hallucination is the brain's reception of a false sensory input, and a person really is experiencing an event through one of their senses that isn't actually occuring

I attached the venn diagram of drugs...notice cannabis is right in the middle :thumbsup:
What is a false sensory input? Surely the term hallucination implies that there is no sensory input. Perhaps though all hallucinations do have some sort of sensory input and it's our perception of them that causes the distortion of reality. Certainly though, when I am stoned and I close my eyes and suddenly i see a dragon flying through a dense forest, it is NOT real. Still can't discount the possibility of a sensory input either. It is very difficult to completely isolate yourself from any sensory input. The creature in the One video by Metallica came close, but even then spiritual energies could be channeling themeslves through his chakras as he lay there on the bed.

How do you know anything you see isn't a hallucination?
