I don't think I cross my leg when I sleep, also I encounter being sat on a couple times sleeping on my side; I thought it wouldn't happen when I sleep on my side but it did. When I get sat on I fight with my spirt, it's like I close my eye and concentrate somoning my spirit out to fight it. I can also feel a little pain after the fight when I'm fully awake.
Once when I was sleeping on the couch at my inlaws and I felt it on top of me, I try screaming but it never works so I close my eye and told my spirit to fight it, I was fighting it face to face in the as if it was a dream but it seem so real because I can see the surounding and myself on the couch as I was fighting the black figure fist to fist. As I was fighting with it, it loss and took off; that's when I opened my eye and told wife to put her arm on top of me bcuz that usually helps me not getting sat on.
It hasn't happen in a couple days now because my mom brought some strings and knifes to a uncle to do some blessings on them, I was told not to open the knife case and it's under my pillow.
Another quick story:
My wife used to say that I was lying about getting sat on and stuff like that until it happened to her. We were in Milwaukee hanging out with some friends and my brother was seeing his girl down there and it was around 10pm when we left Miltown and coming back home. I needed to pee really bad while driving on the highway and some reasons most gas stations were close but there were a rest area up ahead. There was no car at the rest area but I really needed to pee and I was always hear stories about rest area but I had my brother with me so I wasn't scared, but my wife went in my her self bcuz she brave like that. So when we got back home she went to lay on the bed, while I went to the car to grab some stuff; out of nowhere she came out running towards me all scared and shit. I had a wtf reaction on my face. She's all holding me tight and said that something sat on her. I was telling her now that's how I felt and I laughing in my mind because she always say that I was lying. To this day she hates thinking about it.
