People who experience spontaneous out of body report a body shape that is usually an exact double of their physical body.
People who experience deliberate out of body report a body shape that is altered at will.
People who experience deliberate out of body also report a type of joining to the body such as a silver cord.
There are also many similarities between the two.
Both experiences report an increased sense of energy and vitality.
A much higher sense of sight and hearing.
Strange sounds such as loud bangs.
An altered sense of vibration of the consciousness.
