Black Moth followed by curtains moving completely open and closed (violently, several feet within 2-3 seconds and repeatedly)!!!

Short version: was in a hotel for a few hours, black Moth showed up on 5th floor with windows that don't open. As soon as I fell asleep, curtains that I completely shut before falling asleep kept moving slowly and then violently once I realized I was scared. Even happened a few hours later.

Detailed Version: I'm at a hotel and I was just hanging out, watching TV. After a couple hours, a good-sized, very black moth starting diving down from the ceiling from the direction of the window. I don't know how the moth got I but in because it was on the fifth floor and the window does not open. I lost the moth, and then a couple hours later, it landed in the lampshade and I hit the lampshade to scare it out and it seemed to get very angry like a bee or wasp. Later, just as I had barely fallen asleep, I heard a noise and then heard it more. I turned on the lamp and I noticed the curtains were slightly moving. It was two panels of room darkening curtains that I had closed completely before I went to sleep. It was creeping open and closed (in varying increments and speed… Closing a little, or opening a little) to the point where they were completely open. This all happened with in about five or 10 minutes, (from completely closed to completely open). I thought maybe the A/C was blowing on it and making it move on its track, but it would have moved shut if that were the case, because the AC unit was below and to the right so it would've only been blowing in one direction toward the curtains, plus they were heavy and it did not explain why they were opening and shutting instead of moving in one direction. Then, when I started to get really creeped out and got out of bed to get dressed, as soon as I started to get dressed, they started closing and opening completely (each panel moving 2.5 to 3 feet toward the middle then opening completely again) over and over quickly. Like it took 2-3 seconds for them to close and open completely and kept repeating about a dozen times before I was able to leave. It was it almost a violent speed. I felt like it came straight out of a horror movie!!! It got more violent as I got more scared. I was trying to get my shoes on and video it at the same time. I pressed "video" and filmed it for maybe 5-10 seconds. Then I went down to the front desk and while I was looking at the video, I saw that only the part at the very end where I put the phone down (last two seconds) showed up. I didn't press any buttons other than record at the beginning and once more when I was leaving, to turn off recording. So, I don't understand why the important part of the video did not show up. They front desk got me a new room, but then I was even scared to even go there. The security guard came to escort me while I packed up my stuff from the creepy room and as I walked in, the curtains moved about 4-5 inches, quickly then stopped as soon as he walked in. He saw it, too!
But, after the curtains first moved a few inches when we walked in, they stopped moving the whole time we were in there 7-8 minutes packing up my stuff., (though they were moving violently when I was there alone and for a good 15 mins). I know I wasn't imagining things and even the security guard caught a glimpse and was freaked out. As we were walking down the hallway after everything, I asked the security guard with his name was and he said Angel. I joked that I really needed an angel at that time, (another funny sidenote… I checked in on May 21st and the room number was 521). Needless to say I stayed in the lobby all night until dawn. I had a friend visiting from out of town later that morning and she came to look at the room with me, (I still had the key). I propped the door open because I was scared to go in. We walked in and stood there a minute or two and nothing happened we looked closer at the curtains and did find a motor attached up behind the curtains near the ceiling. So, I was really relieved that the curtains were attached to a motor, thinking that explains why they were moving. We found the control panel and pressed each button by itself and in combination and nothing made the curtains move. Even tried walking in front of it and waving their hands to see if it had a motion sensor. No movement. Then, my friend is in the hallway at this point and we were both leaving, satisfied that it was just a malfunction of the motor. She was already in the hallway and I turned back to look at the curtains one last time and they moved several inches. She was able to hear them (her back was to the room) and obviously heard me say that I saw the move again. The only time something would happen was it when I was in the room alone looking at the curtains. So, although finding out that there was a motor made me feel a lot better… It did not explain why it only started acting up JUST as I fell asleep even though I was there for hours or why it would go in varying increments in different directions or why it started opening and closing violently immediately AFTER I realized I was really scared and going to get out of there and started getting dressed. It also does not explain why it would only move when I was there by myself and would stop when others entered and start again as they left. So, between the mysterious black moth, the erratic nature of the curtain movement only at specific times, but hours apart and the security guard verifying he saw it...does this still sound paranormal to you, despite that it had a motor? Does the fact that the security guard's name was Angel seem significant, (I am not religious, though I do believe in God)? Does the room number 5/21 date association or 2:15 a.m. seem significant? Does the fact that it seemed to feed off of me and stop when other people were present seem significant? Years ago, I had weird things happen at a house I was staying at that involved electrical appliances, lights, etc. But, those did not feel threatening. The thing that happened at the hotel with the curtains felt very much threatening. I'm scared it might follow me to my house. Please tell me what you think.
