Four incidents in an apartment: dog, light switch, pistol, and parquet

1. About 4 years ago I woke up at night several times and each time I saw my dog in the room, the one that lived with me at the time, she was just walking around the room, sniffing something, just rummaging in things, each time I just ignored it, well who knows maybe she can't sleep and I just woke up from her rustling. The last time when I opened my eyes, I saw her sitting in front of my bed and looking slightly away from me, I got extremely creeped out and I just said something like "why aren't you sleeping?" at that moment I felt the blanket next to me slightly sink, as if someone very very light sat down in the spot where the dog was roughly looking, I lay there fucking stunned from this for a couple of seconds and then quickly went to another room to sleep

2. During my second year I got a job in the morning for a short amount of time, so I could then go to classes. (not as a drug dealer, but also placed goods in their spots). I had to get up early, around 4 in the morning. In my room the light switch has two sections, so only one of them works: the right one, my whole life as far as I remember, however during one of the first such early outings when turning on the light they seemed to swap places, that is the left one turned on the light, and the right one didn't react to pressing at all, although neither before nor after this did anything like that happen, I noticed this simply when I tried to turn on the light and it didn't react, then just in case I decided to check the second button, maybe I mixed them up and lo and behold the light appeared. When I got home I checked everything again and it swapped back to how it should have been, idk what that was

3. This story is really about nothing, but let it be. At around age 10 on the windowsill in the living room I had various lego builds, there was nowhere to put the sets, so they were stored there. One time I was standing by the windowsill and sorting through some figures, when suddenly a small pistol lying nearby started rotating in jerks in a circle, as if someone below was holding a magnet and moving it around the revolver, this stopped after about 7-10 seconds, I examined that place, there was nowhere any threads from the curtains could have caught, in general I also wrote this situation off as some unclear bullshit

4. One of the nights again in my room the floor just started creaking out of nowhere (some ancient parquet, probably from the 70s). Not even creaking, but really cracking, the sound and area of the cracking boards grew with each second, as if a herd of gypsy ghosts had walked across it. The only assumption is that a couple of weeks ago instead of a sofa I put a bed, and also in a different place, and the spot pressed down by the sofa for many years started cracking abundantly due to temperature changes since it was winter
