confused

[Dylan L]

i had something really weird happen to me when i was laying in bed the other night...my whole body tensed up and my leg moved uncontrolably, i think i lost my vision for a few seconds(cant really remember) my ears popped like when your in an airplane but it was 10 times worse, and i felt a weird sensation in the back of my neck/head...it really freaked me out and i have no idea what happened...it lasted for a few seconds and i came out of it confused...anybody have any input on this??? thanks
