Entity Or Paranoia?

All of this started when I moved into a new house after my parents split up. The house was old but spacious and the rent was affordable, so my mom and I decided to move into it. It was also very close to my school. So the first night I spent in my new home was unsettling. I happen to be the type of person who would fall asleep very quickly and I had a lot of difficulty going to bed. As in, I was exhausted from moving, but I still couldn't sleep. I shrugged the feeling off, thinking it could be the new house and furniture and unfamiliar surroundings. But flash forward to 5 months later and I still couldn't fall asleep easily in my room. But if I tried to sleep in my mother's room or the living room, I would be asleep in a minute. It was just my room that gave me the creeps. I would also like to mention that I would constantly hear dogs barking and cats screeching (There are 9 dogs in my lane.)

Due to all these disturbances, I began sleeping in my mother's room. Everything was fine and dandy. I could rest without any problems. But I did have the occasional feeling of being watched. About a year later, I decided to occupy the room once again. We got new furniture and I was comfortable in my home. I could sleep easily too. But now, the problem was that I was being woken up in the middle of the night and let me tell you, I actually slept through an earthquake once. Nothing could wake me up (unless I was sick.)

I would wake up at odd hours like 1:00 am and 2:45, sometimes even around 3:15. It creeped me out and I could feel someone staring at me. I couldn't see anyone, but I felt a presence of a tall man, standing near the door just staring at me. He never entered the room, just stood there. I still get goosebumps thinking about it. I wear a talisman around my neck and so, I held onto it and chanted a prayer that I was taught in Sanskrit. I willed myself to go to sleep. I told my mother and she dismissed it by saying that it could be my father. But my father is still alive and this man's build is lean and tall, whereas my father's build is tall and larger.

I told myself that it was fine and even if it was an entity, it wouldn't hurt me and cleansed the room with sea salt. I don't know what or who that entity was and it confuses me to this day. I hope someone can hopefully shed some light on this issue. Thank you.
