Lost

I don't remember when I first knew that I was lost to the world, I live in a void,not sure where or why,but inside, I know this is true. My eyes are clear, my hearing good,i should be easily understood, But nobody sees me, nobody hears,if I touch them my hand passes through. I thought I was dead but my body feels warm, I see green grass, I smell the sea, why can nobody hear or see me, I wonder. I laugh, I cry, I have loved and I have lost, did I just float away or am I lost? Am I a fragment of someone elses imagination, a scrap of the past in space? Why am I trapped here and how do I leave? Am I an electronic blip placed in a host? Am I nothing more than a ghost? Will I appear someday or am I forever lost?
