No drugs, no alcohol. I remember vaugely some ideas as to who I was with.   Haven't been sleeping well- been getting a lot more sleep paralysis than usual. Heard a voice say hello which I know wasn't real. Been feeling more off than usual. Sorry, there's so much to explain and I'm not sure I have the words for it. 

If anyone has some advice or some idea about why this has happened I would really appreciate it. Also if you need me to explain more, I can try my best to answer in the comments.
