Long story short there is a dispute between my upstairs neighbors (a couple) and I and it has escalated to the point he is somehow attacking me from above. The situation is worse than you can imagine.

When I lie down in bed, I feel downward pressure pushing my head down into my pillow to the point where the back of my head hurts. My chin is also being pushed downwards and I can also feel pressure around my eyes. When I rest on the side of my head, there is pressure felt on my neck to the point I have trouble swallowing saliva.

While this is happening I can feel them moving around above me like they are shifting their feet. There are no sounds, however, except for the occasional floor creak.

This sensation is also similarly felt when I am working from my desk. Somehow my body is being pulled back hard, so hard that it hurts. It's the same sensation as sitting in a car that has stopped and then suddenly begins moving forward. If I sit up so that my back isn't touching the back of the chair, my body is being pulled back so that I am sitting back. It's like a magnet is pulling me back.

This has been a recent escalation but for the past few weeks they were attacking me a different way. I believe they were using the weight of their body to shift from side to side and literally moving my body to sway side to side. At times they have done this when I am vulnerable such as putting on pants or sitting down on the toilet. This has caused me to lose balance but not fall.

My hypothesis is that since the floors are connected to the walls, which are then connected to the ceiling, it is possible to make movement felt by your downstairs neighbor. By leaning hard to one side, pressure could also be exerted - maybe?

What physics are at play here? Or could they be weaponizing some device perhaps a medical device. I mentioned the feeling of being pulled back like a magnet when sitting in my office chair.

There's nothing for me to use as evidence if I were to go to the police. My only idea is to video record myself when this happens, but it's still a long shot.
