When was I last home ?

I got something in my head something sleeping in my head
 That I don't wanna wake up, you see
 Something in my head and my lazy little body
 Isn't ready yet to set it free.
 Well it's some kind of hibernation who will ever force me out
 With a polar bear up there how am I gonna travel light?
 I got something in my head like a lion in a cage starving wild-
 And i've ran out of meat
 Something in my head something crawling like a snake in
 my bedmade
 me rip off my sheets
 Well it's an awkward situation trying to fight the jungle alone
 But I gotta make my way through if I wanna travel light
 Lately I've been walking away, floating like a song in the air
 Lately I've been trailing away, I've been walking my way
 I was standing on the edge of a mountain of clay
 And I got tired of wading through the mud
 So i jumped to hit the ground it was firm yeah it was hard
 But I stood proudly up with my pain
 Now I don't care about the scratches as long as I'm alone
 here, now
 Broken bones but empty head I made it on my own this far
 Lately I've been walking away, floating like a song in the air
 Lately I've been trailing away, I've been walking my way
