When I was a young child I experienced an OBE while I was standing, awake and fully conscious. I remember seeing my body, and it looked very strange and surreal. Some time after this, I discussed this with my mother, who then told me that my father told her a story very similar before I was born. Later as an adult I experienced several other OBEs, and various lucid dreams. IMO, lucid dreams are not always a precursor to OBEs. My only problem with OBEs as I am to aware of the experience while it is happening and "panic" and quickly jump back into my body. Then my heart starts to race, and it simply reinforces the fact that I don't really know what I am doing when I am out of my body.
Does anyone know of any heredity information concerning OBE? As my father has passed away, I have no way of querying him for information.
