My "idea" of a poem

I haven't written a poem in a long time already and I no longer know the rules. But I felt like making one, and this is what I came up with.

I don't understand their smiles

Their happiness cast no spell...

Where is the melody in the songs that I hear?

All beauty is lost, there is so much to fear

The curtains have closed

All the lights have been turned out

I only have my shadow,

I only have my doubts.

I don't see no color red

Just grays, just blacks, just whites

I've got a broken timepiece

I'm bracing for the heights

The movies don't bring comfort

The drugs don't seem to work

My blood is very cold now

I'm a vampire on a lurk

Tomorrow will be the same

And I will forever be changed.
