I had this happen to me only once, but my eyes were closed. At the time, I didn't know that this was the precursor to having an OBE, so I just enjoyed the sensation - to me it felt like a very pleasant state.
I can relate to you because I am not ready to have an OBE yet, either. I'm too scared!
My dad just told me that he had an OBE and went into space....he said he went so far that he could barely see the earth. He said it was dark and cold and he got scared and went back to his body.
