I’m so sorry this happened- it sounds so frightening, to wake up this way. Are you on any antidepressants? They say it is very rare to hallucinate from SSRIs, but it happened to me. About 7 weeks on Zoloft I started to have the strangest hallucinations just before bedtime. Once I thought my room was filling with water, I ran out into the hallways screaming (in an apartment building in NYC). Another time I was panicked because I ‘didn’t lock the door in the floor’ and kept crawling around on the floor searching for it in a panic (never had a door there). This was years ago now, but it was so real, I was terrified and so, so confused. Went off Zoloft immediately and haven’t had any of these episodes since. My doc didn’t believe me at first because it’s less than 1% that this happens to, but there are millions on SSRIs - so this does happen frequently. Good luck 🙏
