I haven't had them myself, you guys might be interested or reassured by a couple of talks I've seen. One By Robin Murray:

Robin Murray - 100 Years of Schizophrenia: Is This Enough? | Mad In America

He says, among other things, that 9% of the UK population reported psychotic experiences or beliefs and most of these were not troublesome. This happens to lots of people.

This talk by Whitaker is also interesting
