Did you ever feel that someone is in the room with you although you see no one?

I feel the shivers
as a cold chill
runs down my spine.

A cool breeze rushes past
although the windows
are closed.

The cat stares
into nothingness
at an invisible presence.

Is there an entity here
from another dimension?
Something maybe,
beyond human senses.

I feel the shiver
and the coolness in the air.
Is it my imagination
or is someone really there?
