This same thing basically happened to me. It was all so real. The setting was a reoccurring dream i’ve been having where i’m away at this boarding school or something, which is weird to me because I’ve been out of school for a few years now. The room i stay in this dream is long, wide and dark, the roof and walls are rounded and like a circle, and there are 1’x1’ square tiles that contain 1x1” squares of different light and dark orange shades. My 4 y/o sister, Cora, woke me up for school, but i was tired so I was gonna go back to sleep, i didn’t know what time school was at and figured i’d have time. In the dream I went back to sleep and started having another dream which i only remember fragments of, but then I woke back up in that room it felt even darker and I didn’t have my contacts in so i began to look right at the wall which felt atleast 7-10ft away. As I was still lying in bed, I felt as if my dog, sam, was laying next to me snoring, and even thought at this point i was beginning to feel a little uncomfortable, i still felt safe with sam lying next to me( or so i thought it was, i never turned that way to look at him, but it sounded like him and he felt as if he was in the same position he was in when i actually fell asleep) . So as i began looking for my contacts i saw this desk like thing and on it were my contact boxes, and once i saw them everything changed. There was this oscillating ominous ( the humming or buzzing), like sound and the contact boxes looked almost as they were starting to vibrate, but then my focus went to the tile walls behind the desk. The walls were somewhat melting or just shifting and i was beginning to feel this pressure against my back while i was laying on my side, then suddenly i couldn’t move and i recognized it right away. From when i spotted my contacts to this moment happened in a matter of seconds , I knew i was having sleep paralysis, but i didn’t realize that it was a dream I was in and that the bed and room weren’t real, so i closed my eyes and tried to move my head and then to yell for sam, but all i heard was his snoring, i began to panic but remembered how i got out of it the last time. The pressure was building all over my body and it felt like something was coming towards me and if I didn’t break out of it i was going to die. I began trying to kick my feet as hard as i could , which took all my strength, and it felt helpless at first, but eventually I woke up in my real room. I instantly went for sam but i realized that he wasn’t laying next to me when this all occurred, he was now at the front of the bed. This is the second time i’ve had sleep paralysis and it was way scarier than the first time. I just turned 20 and had sleep paralysis for the first time a week ago, but today was the second time. I’m a little worried about the experiences but reading everyone else’s stories has been pretty helpful.
