A disturbance on My Inner Plane

I was in a white space
There was nothing else
Completely endless
With no walls
or anything else
for reference

I could not tell
If i was moving
or standing still
No wind
No horizon

My homogeneous
world, timeless
for lack of differnce
Nowhere to go
Nothing to measure
No reason to think

But then

I imagined
A red dot
growing to
a spot
and this disturbed me

even though
I believed it was not real
