Wormhole falling

I fell headlong down a wormhole
Though laying in my bed
I saw quasars and quarks spinning above my head
And atoms racing neutrinos then colliding
Just then I banged my head
Spun head over heels
Yet still descended
Then I witnessed kaleidoscopic seas
And dolphins leaping from the waves
And birds in assorted colours flying in a circus like parade
Then everything went dark
And I thought this all just in my mind
Before a supernova explosion happened before my eyes
And in a riot of rainbow light
And vision incandescent and bright
Took me on a race through time as well as cosmic space
In and out of dimensions and galaxies unknown
Then I had the feeling that I was being blown
At a thousand miles an hour
And my head was now in a spin
And woke up in my bed left wondering
How did that all begin.
