I think i started to have a tonic-clonic (but not all the way) the
other night. I left a building, started walking, then I felt myself
falling to the ground and heard myself groan. Everything went
black. This could not have lasted for more than a second, because I
never fully landed on the ground, but I felt very disoriented. If
not a tonic clonic it was the beginning of an atonic, but I thought
the groaning happened only during a tonic-clonic. No?
