Is it normal to not to be able to fall asleep sometimes out of fear of dying?
Sometimes I have troubles falling asleep, simply because I'm afraid of not waking up again.
One time, I feared I had eaten too much salt and would die of kidney failure during the night.
Then, I felt like there wasn't enough air in my room.
Another time, I was afraid there had been salmonellae in my dinner and I was going to die of that.
And yet another time I heard a plane outside and thought it was going to drop a bomb.
Is that normal? (When I'm never afraid of dying otherwise?)
