I woke up doing 100ish mph toward the rear of a stopped flat bed semi that was carrying large slabs of stone. Parked in the middle of the highway.
Turned and missed by inches, went into a little slide into the oncoming lane where I saw headlights fast approaching.. Locked it down and spun it off into the ditch to avoid a head on. Almost died twice in less than a second.
Took me 15 minutes to snap out of it.. Sitting in the ditch with my mind racing 3 million miles an hour. I just sat there freaked the fuck out. Semi drove away, car drove off.. It was like 3am in the middle of freakin nowhere. Spun 4 times I think, no idea why I didn't roll over in the ditch. Destroyed 4 brand spanking new tires. I had just installed them the day before.. Had I not, the old tires never would have gripped like that, and I would have creamed the ass end of that semi. That would have been a closed casket funeral.
Lesson learned though, if I start nodding off, I'll pull over and sleep for at least 30 minutes.
