Am I Alive?

I see, but I do not see what is infront of me
I see bloodshed and pain of others in combat

I hear, but I do not hear what is around me
I hear the cries and screams of the past

I smell, but I do not smell what is present
I smell sulfur, gunpowder, and smoke

I taste, but I do not taste what is in my mouth now
I taste the the salt on my lips without a drop of water within miles

I touch, but I do not touch what is on my fingertips
I touch.... nothing, for I am numb

Am I alive?
