Where do faulty perceptions end and delusions begin?

For example:I will often think that fellow posters hate me based on non replies to my post or comments made.Invariably they tell me they don't.Is that perceptual or delusional?

Also what is the consensus on what makes a thought 'psychotic'?
The nature of the thought itself regardless of whether you can see it to be not grounded in reality?

For example: Every once in an infrequent while it crosses my mind that some of the inanimate objects in my flat could come to life and talk to me ie ornaments/stuffed toys.Then i start expecting them to do so.



Although i know that the thought isn't rational/sensible it is difficult to shake off though it does go away after a couple of hours or so.
