Hello everyone! So a few days ago and today I've had what I think is a hypnagogic hallucination, few days ago when I was falling asleep I saw a black blob which looked like a big spider(?) on my ceiling, but after I opened my eyes fully it was just a shadow. I dismissed it but today when I woke up in the morning and was about to fall asleep again, I started to hear some sort of music which I thought was coming from outside (I live in a city and I have my balcony door open during night), yet when I opened my eyes fully and got awake the music disappeared. This made me very anxious because I already have a fear of becoming schizophrenic/psychotic (Sorry for everyone suffering with these types of disorders!). This all started after I quit smoking marijuana which I was doing for about 6 months and I developed a tolerance to it, which indicated that I would get some sort of withdrawals from it. The main withdrawal was of course very bad anxiety and being a hypochondriac already, I thought I was going crazy or developing some sort of psychotic disorder.. My psychiatrist told me that it isn't so but I'm still debating if this is just a prodromal phase of schizophrenia. I'm a 20 years old male (prime age for the onset), never have had any delusions(except intrusive thoughts when having bad anxiety) or hallucinations(except the ones when I'm very close to falling asleep) or any sort of paranoia or any symptoms of the disorders that I'm fearing.. Yet I still find it hard to shake off this fear even though my anxiety from withdrawal has almost completely vanished. It flares up sometimes during the day but it lasts only for maximum of an hour or so.   


Does anyone have any tips on how to overcome this? Or does this sound anything like the things I'm fearing to anyone? Help would be appreciated!
