That dreaming your crashing is terrifing....
Done that a few times,,,pulled over for a kip in the services,,,then whilst sleeping I've dreamed I was driving and falling asleep at the wheele,,,,,it's frightened me so much,,I've woken myself up screaming ,,,if anybody was parked next to me ,,they would have had a good laugh ,,,,the worst bit,,,,is the second you wake,,,your eyes won't focus ,,,and cos you think your driving ,,,it's terrifing for a few seconds...
