I had a strange experience last night. Not to sure what to make of it. I was half asleep or sleeping, not sure, when I suddenly dreamed that I was in my bathroom and I half saw but mostly heard someone that I know is living speaking to someone that I know has died. Next moment I felt intense sensations like electrical current running through me (strongest I have felt to date) I tried my best to intensify them and for a while it worked and I suddenly saw the bathroom from an odd angle very clearly, like in daylight. Felt stuck in my body though and sensations stopped and I woke up in my bed. I had been thinking about OBE when I went to sleep, but I was not trying to at the time.
Ya, This is OBE, but an unconscious OBE, It happens sometimes, your Astral Body travels unconsciously somewhere & gets into conciousness suddenly, This is what happened for you. The sensations like electrical current is the gain in Astral energy, This is why you saw the room.
This has happened to me once, last year when I woke in morning & went to sleep after 10mins, I got into an unconscious Astral Travel, I was in my friend home, He was talking to his aunt about me, I heard that he wants to call ME(couldn't hear much than this) , I couldn't see(Blur Vision) anything else than his black T-Shirt, I got the call immediately from him after that, I confirmed that he was wearing black T-Shirt when he was talking with his aunt.
This happens sometimes when someone thinks about you when you have Astral Projected(Like telepathy).
Hope this helps :D
