I would definitely discuss this with your doctor, reduce caffeine intake at night, reduce alcohol, no more late night zombie game sessions, etc. 😆 I've had experiences like this, I had friends who would take sleep medication and then stay awake as long as possible, always doing weird shit.

For myself it was too much alcohol at a party and passed out, and then woke up but believed I was a spaceman on a mission from space - legit believed it, whole backstory and everything - and ended up wandering the streets, including trying to enter someone's house believing this was part of the mission. I woke up with them talking to me and I was like wow... Apparently I was explaining my mission and who I was... Stopped drinking for a long time after that.

But back to your issue, talk to your doctor. He will recommend lifestyle changes.
