Ok, so from some posts, I get the sense that HI are mostly weird hallucinations, pretty colors, and nonsensical things (similar to an LSD/shrooms trip...?). From other posts I am under the impression that they are more real and logical, however short, 'scenes'. Do both come about at different times? Is it a progression from the former to the latter? Just trying to clarify so I'm not surprised (I'm pretty sure I've experienced HI but I'm not positive)
