Yes I've experienced a lot of variation in the degree of psychotic thoughts... The degree to which I believe them is one factor. A second factor is how much of my time is occupied with the thoughts and a third factor is the extent to which I act or say things based on those thoughts. Since my psychoses are have a big paranoid component whatever I say about the thoughts tends to come out in accidentally as I don't trust anyone. I can however bring myself to discuss the thoughts eventually with my psychiatrist but that is only when the paranoia subsides.

Just as an aside, I think all the negative self-talk and gloom and doom thinking, catastrophizing etc. when I am depressed (this is my usual state now) is also a kind of psychosis but it is not looked at that way.

I've never been manic without a psychosis but have had psychosis without mania.
