Hearing hysterical laughter in my mind

[Slifon]

Just now, something quite strange happened, I was lying down and listening to the autobiography of a yogi with headphones, I was lying down for a long time and after a while, I started feeling movement in the prostate, in the whole back, and a feeling between the eyebrows, at the same time I felt a sensation all over my head that I can not describe but I felt like I was going deeper into my consciousness, like a buzzing but not continuously instead like hits. Because I had similar experiences in the past I had not a problem with that. After a while, as I was listening and feeling these sensations, I started hearing hysterical laughter from a woman, which seemed very strange, at the same time I wanted to stop and to continue, I decided to stop and at that moment I realized that my body had paralyzed my eyes needed force to open and it took a lot of effort to get out of this state, what exactly it was I really do not know.
