I was talking to my friend when he got a brilliant idea like he always does he's idea was to create your own hallucination a person that would follow you around so that you can see... it? or him without any concentration so that this person would be around always (kind of sounds like I'm lonely dose it not?) anyways id like to create this hallucination on purpose so that its only this one person not many (or out of control) but i have no idea if this is even possible without drugs so I'm asking if anyone would be willing to help me or at least point me into right direction

oh i also heard of "beautiful mind" (movie) witch is based on true story that has something to do with hallucinations
