After reading some stuff about astral projection, it seems quite similar to what I've experienced. This is not the first time that I have tingling sensations in my hands, the first time I stopped quickly. Last time I stop myself when my timer stopped, I didn't pushed it too far actually. I'm not even sure about what I'm going to say, but I think that I have a memory of a top view of my scene, but I don't remember any view my body.
