Lost : Where?

Where did I get lost?
Was it among my dreams and desires, or,
Was it among my fairy tales?
Was it in my playground, or,
Was it in my mental battleground?
Was it in my video games, or,
Was it in my history textbooks?
Was it Lavoisier, or,
Was it Einstein.
Where am I?
For I see myself only with a past and there's no light at the end of the tunnel.
