Kundalini Awakening

I remember I had this experience a few nights ago. I was sleeping in my bed at night, and had that sensation as if somebody connected my spine to an electrical outlet. Initially this feeling was weak, at the base of the spine, it made me conscious, but I still was asleep. The sensation of electrical tension traversed along my spine making me "unfold". I mean, I was lying in a fetus position, but as I got that immense current running up my spine I was forced to straighten up my spine, even bend it opposite direction, by expanding my chest and leaning my head backwards.

This current was tensing my whole spine, and the sensation was stopping at my throat, it seams there was a blockage at my 5th chakra, so the current could not pass. I almost panicked at that time and was afraid the current will pop the blockage like a cork and continue to my brain. This caused me to wake up and the experience ceased.

I recall having very similar experiences before, but the current was able to travel up my spine up to the level of my navel, which is the 3rd chakra. It was trying to overcome the obstacle by bouncing up and down several times. That was a pleasant, but at the same time scary sensation.

Only later I understood that was the mystic Kundalini or, in other words, latent nervous energy traveling up my spine, I was glad I could remember this experience.
