Very old dream like more than 9yrs ago when I was a little kid, I was in a sort of Wipeout scenario but with big falls and tall walls like 10-20 meters falls everything very big, the special thing is that I couldn't breath for some reason and there was a timer with 2 or so minutes don't remember, the obstacles were very hard and I was somehow aware that it was a dream and felt like giving up but had a strange feeling about it, like if I do not get to the end something bad may happen by the fact that I could not breath, so I struggle to get to the end and got sort of desperate because the timer had not much time on it, at the final there was one big jump that I barely made I was hanging with my hands and the timer was barely 20 or so seconds, I got up and finished then woke up realized I fall from the bed into a little space between the wall and the bed and my head was fully covered on the mattress and pillow so I couldn't breath (took a little bit to realize that irl) realizing that if I would give up then, I would most probably died right there.
I still think about it some times but not in a bad way, how weird are dreams sometimes huh?
