Near Death fear jolted me into a Lucid WILD door?

Yes certainly. My best guess during that time was that the adrenalin kick, instantly before the accident made my brain go into high speed prediction calculation (since I am an Engineer in advanced calculation ;-), trying to predict very rapidly the outcome in an mental simulation, found that the best way to survive was to grip hard to the handle and in that way make me fly away over the barrier in a spinning rotation (with the bicycle left on the other side). So that I landed on my feet further away on the other side of the barrier and then back on my backpack with my (lucky enough) soft sweater tucked inside. Once the simulation prediction was over, my brain put me unconscious, as a safety precaution, and then once back safely on ground, waked me up, and then this memory of the prediction simulation from my adrenalin kick come back as an "in live experience", or a kind of a lucid dream "OBE" experience, while in reality it was just a memory of the predicted outcome. During that time I did not know that "Lucid dreaming" existed. Later once I knew about it I rethought about this experience, if it could have been something else. This memory is one of the most vivid memory I have ever had of something, most probably from the strong adrenalin kick.

Just to filling in the gap: I had a first accident 10 year earlier with my bicycle on a cycling path. I had taken the same path like for 5 years going to my swimming sessions. I knew it by heart and was often distracted by thoughts or daydreams while taking this road, not really looking where I cycled, but was on a kind of auto pilot. One day the city council had decided to put a barrier to stop cars or motorbikes taking the path for bicycle. I did not see the stoping barrier and went straight into it. I was unconscious for surely half an hour and was really in a bad shape. Anyway this memory had haunted me in dreams for a while. So it is not strange that 10 years later fears hit me when I "once again" faced yet another cycling path barrier in front of me. I mean the day before it was not there! That very day I had bought one of these speed monitors you put on your bicycle to measure speed and distance and I was on my way to the forest to do my weekly training session with my mountain bike. I saw I was cycling in 30km/hour on my monitor and was happy it was working, then I look up an saw the barrier just the split second before crashing into it. Not strange that I got this instant fear of near death.

Now I wonder, based on this experience, could an adrenalin injection while in REM induce a Lucid dream ?
