Laying down one sees the ceiling
Standing up one sees the door in the wall
To assess reality:
Confirm or deny one's eyes are closed
By gently activating the eyelids to press down
The distance they traverse and responsive pressure will reveal:
One's eyes were already closed
Meaning the visions are not optical

Beware false light

The pulsating room
The deadly enclosure
Is of the mind
By the mind
In the mind
For the mind
To constrain cognition
To fetter the self
And avoid the panic of unfathoming
Boundless no-self no-where at no-time
