Schizophrenia

[Mister Obvious]

Again, someone who compares schizophrenia to 'nightmares' that continue in waking life.

Every time I hear this it just reinforces my assumptions...

I believe the area in the brain which produces DMT whilst in a sleep state malfunctions and releases the chemicals which cause these perceptions whilst awake. Schizophrenics are essentially in a waking dream state all the time, and this is why the things they experience can be nightmarish.

We all know that FEELING of a nightmare, or even just a regular dream. That feeling is induced by chemicals in the brain. That feeling is what these people are describing their schizophrenia with and it only makes sense to assume that's because the two originate from the same place/are caused by the same chemical reaction.
