So I'm waken up at around 6am to move my car (I was parked behind my roommate in the driveway), because she had to go to work.
I went to bed around midnight, so I thought "well I've been asleep for the right amount of time, I'll try a WILD."
So I go back to bed, and begin to clear my mind of everything and just focus on whatever random images, sounds, etc. that my mind brings me.
I'm three seconds into it, literally my eyes were closed for like three seconds, and BAM!!
I see intense visualizations of a horizontal tunnel, I feel my body being puled through it faster than the speed of light, and insanely loud sounds of pulsating electricity. This tunnel was made of what looked like beams of plasma, lying horizontally to me; and every time one of them passed me, I heard a loud sounds I can only describe as electricity. But I was heading so fast down this tunnel, that these sounds occurred five or ten times every second. This on top of the intense g-force I felt on my body as I was heading through this strange tunnel, gave for a very intense experience.
Normally, WILDs build up to this, but instead all of this happened at once; with no build up whatsoever, just... BAM!!! haha
Needless to say I was so startled by the suddenness of this, I was not able to get my heart rate down enough to stay in the same state.

I was just wondering if this has ever happened to anybody else.

P.S. I say "horizontal tunnel," because there where no walls; just a floor and a ceiling that continued on for eternity (both being made of those strange beams of plasma).
