Trying Channeling!

For a while now, I've been wanting to try channeling. I understand that it is vital I use caution and protection in the event negative energies want to attach to me.
As I laid in the bed resting, I began to envoke my vibration in order to separate from mind and body... to astral project. I didn't want to go someplace, I wanted to communicate while I was in this trance or astral realm of mine. My energy floated to the ceiling. I was sitting in a meditation indian style position with index fingers touching my thumb. I remember I stopped at the ceiling hoping I wouldn't seep through the roof. It also occured to me that this felt so real, I wondered if it was my body actually floating up instead.
I communicated through my mind, asking to speak with a higher being. I asked to speak to those who were not from this planet, an alien to be exact. Crazy I know, but why not? I picked up a radio station! This is reoccurs numerous times. I heardthe short converstion between the radio jockey and a caller calling in about something. I asked my question again, to speak to a higher being and pictured outer space and an alien being in my mind. I got some woman ranting in anger anout something. It was annoying and I told her to shut up. I know, not nice, but I was in a hurry. I then got a high pitched nonhuman voice. It wasn't speaking English. Strangely, I felt another spirit entity ttying to help me. It asked the alien being to tell me his name. I didn't see either of these being, just felt and heard them. The alien being told me his name, it was something I knew I couldnt remember as it not simple in any way, but it did start with an M and had many syllables in it, like Memachatylem. It possessed probably some sounds English doesn't have. I didn't like the vibes I was getting from it, and I knew it didn't want to help me or communicate with me. My mind ended the communication and OBE's and I floated back down to my bed. I suppose it was my minds way of 'knowing' it was a bad connection and ended it before any 'damage' was done. I'm still gonna try again soon.
