I've actually read a lot about psychosis that says that psychotic people see MORE of reality than people with other kinds of operating methods . . . it's just that we also get so much information from the world (because of all the reality we experience) that we start trying to build systems and integrate it all . . . and when we fail, we get psychotic breaks and hallucinations and stuff.
Apparently people who aren't psychotic are better at ignoring extraneous reality stuff.

Also, my English is totally gone tonight
