I'm not really sure if this is worth posting, Hell, I'm not even sure if what I heard was legit, but I'll let you guys decided.
This happened just this past Saturday the 28th of March. I was on a long weekend because I had put in for time off to go to SC Comicon (I put in for the time long before the rescheduling due to Corona). My PTO started on Thursday and ran through Monday. Starting Thursday night I was having trouble sleeping, something just felt off and I had to sleep with my lamp on just to feel comfortable. Well Saturday night I was up late playing my PS4 when around 2:45 a.m. I started hearing this weird groaning sound right outside my bedroom door. I had my door closed so I wouldn't disturb my parents and it sounded like it was just on the other side.
Now if you read my previous story "My Parents House" then you would know about my experience with the attic and the image from the movie "The Grudge". Well it seemed like Kayako wasn't done with me because the groaning noise sounded exactly like the choking-groaning sounds she made only slower, almost hesitant or confused, I dunno. It was slow like "urggh...urggh...urggh...urggh". This repeated off and on until around 5:30-ish which is when I noticed I wasn't hearing it any more. I didn't time it to see how often it occured during that time, but it seemed to be about 10-20 minute intervals.
I thought it may have been my dad the first time I had heard it since he usually goes to bed between 12am and 2:30am, but I don't know what time he went to bed since I was in my room with the door closed the whole time and after I heard it the second time and what it sounded like I knew it wasn't my parents. I was wholly focused on the game I was playing and wasn't thinking about anything other than that so I know I wasn't psyching myself out when it started. I didn't feel any other sensations other than a steady eerie, creepy feeling.
I tried to brush it off the first few times, but it persisted. There were two times where after I heard it I saw a flash of white in the corner of my left eye. From where I was sitting it had to have come from my computer monitor, like a light suddenly reflected or my monitor fickered on for a split second, but my computer had been off all day and my monitor shuts itself off when there's no signal. I also had my main room light on so it was pretty bright in there so a flash would have had to have been really bright to see it. I didn't look in that direction to affirm anything because I didn't want to possibly see something I'd regret. I kept looking at the bottom of my door though, expecting black hair to start creeping under it at any moment.
Needless to say I didn't sleep at all that night. I didn't even leave my room to use the bathroom until about 8:30 when there was light out. I was worried a bit about my parents since their room is right next to mine, but I couldn't bring myself to open the door (real brave of me I know). Though I did hear them snoring a few times which made me feel better. I didn't hear anything Sunday or Monday night, but I still had to sleep with my lamp on to feel comfortable.
