Weird symptoms during trance

[MuxMG]

A weird manifestation during any trance is a kind of vibration in my underbelly (not to say p.n.s ). This vibration is modulated with the speech in the file. So each word, or syllable, that is spoken resonates there.
This is so weird and distracting and I can't seem to get rid of this symptom. This is not arousal or exitement, it just happens.
Concentrating on the file helps sometimes but it keeps coming back quite often during trance and even sometimes while awake.
Any ideas?

I assume you have checked the settings for bass, etc...? It almost sounds like some sort of resonant frequency thing to me, although I'm not certain it would work like that. (Gah! Been out of school too long!)
