A Blue Door

Stuck and feeling uneasy, what exactly is this place?

Got to get out, a brisk walk turns into a run, frantic pace.

Oh no, not really understanding my current situation,

Chequerboard floors everywhere, I'm not a Freemason.

Silver men pop out of the ground and try to grab my legs,

Is this whole thing a hallucination, I don't take any meds.

Spot an opening up above, a blue door of colour appears,

Reach it, jump and turn the handle, time to face my fears.
