That sinking feeling
Type of Spiritual Experience
The sensation of sinking is widely reported in out of body experiences. This phenomenon is more common than expected and often evokes a fear response because of the unusual results. It is not unusual for out-of-body explorers to sink through their bed or even the floor. The key is to remain calm and mentally ask for awareness and control. We must remember that when we leave our bodies, our physical surroundings are no longer the prevailing reality.
A description of the experience

It seemed to happen when I would be napping and I would awaken with the feeling that I was sinking away and was about to lose consciousness. I would be so scared, for it was such a strange experience. It got to the point that I was almost afraid to lie down in the afternoons, for that was always when it happened. I even considered this to be some type of seizure, but after about eight of these experiences they ceased, and I have had no more.
