Pseudo-Entites in Schizophrenia

Is it possible to interact with someone who is not there in reality? Here, I don't mean the trivial case of invoked sand box, crossover or install box - but a person who seemingly comes from the chat box itself.

It used to be possible - but now, I believe that the possibility has been removed.

It's possible to check if sand box, crossover or install box is operating, if you still have doubts.

Furthermore, is it possible for the connection to get corrupted, receive something that the sender did not say? It used to be possible - but I now believe that the possibility has been removed.

However, there is a caveat. If you are talking with a past version of you, this problem of receiving something the sender did not say persists. This is always a crossover - you should check if the information you received is a crossover.
