About 4 or 5 days ago I was attempting a WILD, and I entered SP for the first time. It was an extremely weird experience, and it scared the hell out of me. As I was laying down I didn't really feel the "blanket or heaviness" that people say they've felt, but I hear a really loud noise on my ears. It was like two airplane engines right inside my hears. I also kind of felt like I was floating at a 45 degree angle and I couldn't really feel my bed. I knew it was SP so I knew not to get to excited. I couldn't open my eyes, and after a minute I could feel and hear a lot of bats entering my room through my window. Of course they weren't real, but I could hear them and feel them fluttering around me so I started to freak out trying to get out of it. After a few minutes I broke out of it and I could start feeling my bed again and all the noises went away except my stereo, which I went to bed with on. It was an exciting and weird experience that I'd like to try again.
