Dream About Chased By Strange Man In Museum

It started with 2 different people I knew from separate areas of my life. 1 who went to my college and the other I met from joining dance club. It all started off with us laughing (me and the one from dance club and a group of others I did not know) We went on a group tour around this strange museum (everything was a light orange colour wood. Then at one point my friend from my college was hiding something and he didn’t seem like himself at. So I told him he could tell me and I’ll cover for him whatever he needed however not long after he disappeared and there was a small white note which ended up being a letter with used Blue pens. I don’t remember what the actual letter said apart from the fact that my signature was frauded onto the letter… it said “love from (with my name on it instead of his) “ Next thing I know I lose my group in the museum tour so I go and end up looking for them then this strange middle age man (who looks like he’s in his 50s and wearing shades of similar taste to Jeffrey Dahmers) stops me and grabs my wrist constantly telling me I need a pass and I end feeling confused. When he grabbed my wrist I felt like he was targeting me so I asked him to let me go and he refused when he grabbed it it was tight enough to kind of hurt. I ran off and he chased me through 4 different corridors and 2 different rooms. The final place I went was the ladies toilet. I opened this small door inside the toilet and sat and hid behind there then I peeked it was a different man this time but then thought to myself he’s a man why is he in the ladies toilet and not the man’s? So not long after he leave’s silently then I gently hear the door slam so I believe it’s safe to go back and look for my group… I was wrong it was the same guy who chased me and he had that AHA smirk on his face. I got so scared he tried to use excessive force that dirty cops have used on their victims in the past however I noticed he never worn a police or securitys uniform. I have also never seen this guy LIKE EVER in my waking life. Then I woke up with dread. It was very very random dream that came out of nowhere.
