Definitely you cannot accept anything as reality. Certain experiences can be accepted as "real" while others cannot at least in my life experiences. I can say that I have had paranoid, strange ideas that simply made little to no sense. The key is to know which things are basically positive beliefs and what things are negative. Of course, "positive" beliefs that are excessively grandiose (thinking your some kind of great figure, prophet or some sort, headed for fame, etc.)are not be good either because that can come across as very stereotypically "crazy". Otherwise, having positive beliefs are generally potentially beneficial. You could look at it like you have had a sort of religious awakening rather than psychosis.
