It's interesting. I have done yogic things for a long time and had several notable experieces: firstly I experienced my mind absolutely in sync with my dog for a brief moment. Anotherwords, you could say I was in the dogs mind or vice versa--I experienced her joy with the food I was briging. I also experienced a persons body of some sort, in mine. It wasn't a psychical but it was some aspect. Prior to these events, which happened around the same time, I had a feeling of being emotionally lost in my life, like confused about what I was doing and who I was. I feel my mind was experiencing a "non-attachment" to itself, and somehow released itself from it's normal parameters. There is plenty more but that is most pertinent. I think these dead people--their minds may be essentially in a spiritual state that is unsure about the next step. The body is dead but the mind is witnessing this totally conscious. I have had this experience in sleep--my mind totally awake but body sleeping. Yogic. In this state the mind of a dead person only has to will to leave, until then it is in it's body. But then again the spirit stays around the remains, which is why grave sites are considered sacred. My sister's ashes buried outside churcho--I heard her voice once when I attended a service there. Her spirit is still around it's remains. I'll take a sea burial  I like the fish and scuba diving.
