They'll make you see the state of your own mind. Literally, they throw noise into the normal visual system and cause memory and emotional state to bleed over into the visual field. It's a good way to monitor your own mental state, if you start seeing horrors that's a reflection that something is bothering you. This is why traditional users of psychedelics would screen people for mental illness before group sessions, and why it was not uncommon in those societies to have a 'mentally ill' person take a large dose of psychedelics while having a half dozen people around them to make sure they didn't hurt themselves. "We do not see things as they are, we see them as we are" "In a dream, we see only what is reflected by our own thoughts" Now if you have a state of complete mental equilibrium, you won't see much from taking psychedelics other than an intensification of colors, a sharpening of edges, and an intense interest in everything you're seeing.
