Hide and Seek

I played hide and seek a while back,

I was looking for a hole, a dent, a crack,

It has been a while, weeks, months, maybe years,

I have no idea, no clue, I am gone it appears,

I looked in the mirror but I have no reflection,

A vampire ? me? No way! Natural selection?

Away I am, seen by no-one, a ghost, a specter,

Can I be seen by the tax collector?
