As soon as I begin to sleep; images, thoughts, memories pour through my head
It's immediate. Even when I'm just lying on my desk trying to nap. Yet I can rarely ever recall what i was thinking or seeing and am left confused. I feel like I'm having a bunch of dreams, since I can never remember them afterwards. It can occur as soon as I go to rest while being driven in the passenger seat of a car or taking a short nap. I've also become lucid just seconds after taking a nap. I feel like my body skips the first phases of sleep and heads right into REM. Does this make any sense?
