Where to begin... Well I have been working night shift for years and when I get home I like to unwind a bit and I don't actually go to bed until around 5am. Over the last few months I've noticed myself waking up and hearing a change in the fan noise that I have on. I sleep with a fan on because it blocks out the rest of the noise (I live in an apartment with noisy neighbors). On several occasions I'll feel the air flow being redirected like someone is standing in front of it. Several times I have felt what seems like a cat or small animal walking around on my bed. It feels like it walks around me while I'm lying still, I feel the blanket pull like there is weight on it.
On a few occasions it felt like it would jump off and then jump back on. Once I woke up and reached for it but of course I grasped nothing but air. A few times, I felt the entity touch me on my back. It never hurts me or anything. Some people told me it's just my brain playing tricks on me because I'm usually in a half awake state. Sometimes it feels like it is touching me in sexual ways. I don't really feel scared by it but more or less annoyed. I also sometimes hear it bouncing of things in my room.
This just started in the last few months. I have been living in this apartment for over 5 years and haven't experienced anything like this before. Am I going crazy? Is it some kind of sleep disorder? Or am I being visited by some playful spirit that just wants to play games with me? Any help would be much appreciated.
