I had agreed to be transported somewhere while in a tight and airless space. It was like a car, but I was pressed against the window, and we were supposed to go under water. I tried to practice yoga technique, telling myself I would be okay holding my breath and won't suffocate, and I shouldn't panic. But I guess I did panic because I woke up.
I went to the bathroom and temporarily forgot the dream. But then when I went back to bed I kept having trouble breathing and was wondering why I was upset. Then the dream came back to me.
The thought that first came into my mind was I must scatter my son's ashes - he shouldn't be in a box.
Then I thought: maybe this is what he went through when he died. Did he dream he couldn't breathe and he couldn't wake up?
