A dream of falling

I have this dream, of falling into nothingness.
I open my eyes, to see nothing in front of me, as I fall into the endless darkness that is in the middle.  Looking to my sides, buildings, forests, mountains, deserts, frozen wastelands, and everything that I have ever seen, or imagined, speed away from me, as I accelerate until I am but a spot of light.
Then, after what felt like an eternity of crushing pressure, wind, and pain, I hit the darkness and explode.
Then I wake up, feeling nothing but ease, and relaxation, like the nightmare I just had, washed away all my worries, anxieties, and problems, allowing me to focus on the present.
The dream of falling is terrifying when experiencing it, but afterwards, it’s the cure to my overthinking, and anxiety, which often put a stop to my tries of getting better.
