Question: is it possible to become stuck in the 'psychedelic space' indefinitely?

Im not sure how to describe the 'realm' one arrives at when taking a really high dose of psychedelics, but from my experience it felt as though I was transported into a different dimension completely disconnected from the physical world, which is what I refer to as the 'psychedelic space'. My biggest fear is that I will be stuck in this space indefinitely, with no way to return. I understand that people have experiences of developing HPPD and psychosis, but it doesn't seem as though they are actually persisting in the realm itself. So I just want to know is it possible to become stuck there?
