Last night, I dreamt I was sitting at a table in a school hall/canteen when there was a sudden WHOOSH and my perspective/consciousness flew out of the back of my head and away, I could see the dream scene from above.
In the dream, I thought my head had actually exploded and I'd died, maybe my subconscious remembered reading about EHS and created a dream narrative around it when it happened?
I woke up feeling so shocked but my heart rate was fine.
