My personal experiences didn't occur in pj though and I'm not sure if these experiences are related to ghost but I'll share anyway and let /k/ be the judge

Growing up, I've encountered numerous incidents whereby my names were called out loud yet no one was actually there. It happened quite frequently so I'll only share some of them..
First incident - when I was around 9 years old, I was alone at home late in the evening doing my homework while watching the tv. Then I heard a man's voice calling out my full name faintly and repeatedly. The voice originated from inside the room but from direction of the balcony door. I pretended not to notice and turned up the tv volume in hope to cover the voice but the voice only grew louder and louder repeating my name until it slowly turned into a screeching high pitch sound as the tv volume went up and up. I ran in terror to the stairs and waited until my aunt came back (my parents were out of town) before I dared to move. I didn't know where to go or hide. TT
My aunt didn't think of anything supernatural but instead was more worried of robbers/thieves. She checked nothing was there so she laughed it off that maybe someone outside was making fun of me but I'm very sure the sound came from inside the room, not outside at the balcony although it did come from that direction. So...
Second incident - very similar to the first incident but this time, the voice came from the fan which was more eerie than the first incident. This time, I was lying on my bed about to sleep so the tv was off and I heard the same voice over the fan screeching my name from slow to fast pace with the pitch tone getting higher and higher. I stormed out the room and slept with my parents instead that night although I acted cool and didn't tell them anything.
Third incident - growing up, I got used to such man's voice calling my name at random times that I began to suspect that it might be all in my head so I didn't really share it with anyone else. Until one day, my cousin, A, same age with me around 10 or 11 came over to my house. As we were playing my computer together in the living room, both of us heard someone yelling my name from the kitchen (imagine how loud it was). Spontaneously, both of us ran to the kitchen but no one was there. My mom was in the kitchen bathroom washing some clothes so we asked her who called for me? And my mom gave us a weird look and said that she heard nothing at all. Immediately realizing it was that voice again, I asked my cousin A did she hear someone calling my name? And she said yes it was very loud while being puzzled on why didn't my mom hear it and she checked the whole kitchen, no one was there. Phew, alas someone else heard that voice and I guess I wasn't crazy.
Fourth incident - I was in a shopping complex in Ipoh walking with another cousin, B, and a distinct unusually loud voice yelled my name once from behind. Instinctively, we both turned around but there were almost no one behind as that floor was quite empty at that time. Feeling spooked, my cousin and I looked at each other and hurriedly left that floor. I was wondering if I was stalked?
There were more incidents like this until it stopped at my age of 15 or 16. Although the voices were gone, I still heard footsteps walking around my bed everyday until it became a norm for me. At least footsteps were nothing compared to those voices yo. I also kena sleep paralysis almost every night (sometimes twice per night) to the point it became very very tiring for me as I was always unable to have a good sleep until I finally left my old house to pursue my studies in another state at the age of 18.
Fortunately after leaving that house, I never kena sleep paralysis or heard any voices or footsteps anymore until now.
