Oh my apologies if I was incorrect. I looked up a few definitions. I most definitely was delusional during that time and very much in my own reality. No I don't think the delusion is required to be dark to reach a level of psychosis. But of course that is only my opinion

.psy·cho·sis "sīˈkōsəs" (noun) -a severe mental disorder in which thought and emotions are so impaired that contact is lost with external reality.

psychotic mania - has poor judgment with impaired thought processes
