This happened about 3 years (specifically in 2015) after my family members and I moved into our new home from Canada. I was in middle school (7th grade specifically) at this time of year. I was chilling on the couch in the game room on the 2nd floor of the house. I was in the dark because it was almost 10 pm during the winter time. I was watching CrashCourse videos on history on my phone because I thought they were interesting at that time, and I was kind of obsessed with history during middle school. After a few videos, I felt a sensation that someone was watching me through one of the small windows beside the couch that was around a foot or foot and a half above me.
I looked up at the window and saw a man's face. He had a wide, toothy grin. He was a bit see-through but he had a slight pastel blue tint or outline to him and was kind of balding in some areas of the head. What stood out to me was his eyes because the eyes looked really bloodshot and really red compared to what I have seen in the past. His neck looked really damaged as well, like the neck looked like it had surgery done on it multiple times and the neck seemed a little bit crooked. I originally didn't process what I was looking at but after the initial shock, I got off the couch and started to back away towards the door of the game room. His head slightly turned sideways and started to smile even more (to the point it looked like it went up to his ears) while still looking at me and starting to drift away from the house. There was another window a few feet away from the one above the couch. I could still see him drifting through the 2nd window. He disappeared when I looked through the big window behind the couch.
I ran back to my room after that and I didn't tell my parents because I knew that they wouldn't believe me because the both of them got their degrees in STEM and didn't believe in the supernatural.
Welcome Martyani, you handled this really well considering the bizarreness of it. Bit of a gruesome thought but I wondered if the man had died of hanging, might explain the injuries on his neck and the bloodshot eyes. Wish I had an explanation of why spirits show themselves like this to people. Can only imagine this individual was getting off on scaring people, either that or he's deranged, stuck in some horrible time he experienced while alive. Wonder if anyone else has ever seen him. Seems like he couldn't get into your home too. No doubt a good thing.
Thanks for sharing.
