last night I was dreaming normally when I suddenly realise I am dreaming, a man appears and says "when was the last time you did this" and then a very high tech helicopter cockpit appeared, I said "Never" and he looked back and then we banked to the right. I woke up soon after this point and woke up in a real state of paranoia, I had a panic attack which took 30mins to subside. I was just really freaked out. For most of the night however it had definately consisted of the nightmare type of dreams, the ones where although the dreams are not bad they are really worrying/scary/uncomfortable to be in. Is it possible the LD caused the panic attack after I woke up?
