I have heard spiritual language of "entering another dimension". I have an experience that is not connected with sex, but it was at a time I was caught up within extreme emotional turmoil, trauma and agony. I laid down to sleep. When I looked at the clock afterward, only 19 minutes had passed. This was not enough time to have fallen asleep and to have dreamt deeply. But yet I observed my body laid out horizontally, face upward and appeared only as bright, energetic, glowing light in a space filled with only white light. It was perfect peace and stillness. It seemed like I had been gone much longer than the clock indicated.
I appreciate that you would share your amazing experience!
