Yes, in my opinion it can.

I'm not exactly sure what you mean here, but anyway:

I know of three people. They had all been LDing for about eight years, when it all started to go very weird. They started to find that they could sometimes "see things" in their peripheral vision whilst awake.. they started to hear voices while awake too.. and staring at anything would make it morph into sometimes strange and scary things, like animals, birds etc.

Now.. if that sort of thing is happening to you, what else would any Psychiatrist say? Classic symptoms of Schizophrenia.

[One of the three people just accepted that it was happening, and went mad in a sober fashion. The other two ended up with shrinks. One didn't mention the visual and auditory "hallucinations" and was given anti-depressants. The other one told their shrink everything, and they were sectioned for 6 weeks and diagnosed as "Schizophrenic"...]
