We used to have it all, it was us against the world But now, I've been sleeping on my own Spending all these nights alone, knowing you're not coming home Cause you're running through my dreams It's like you're on repeat Feels like eternity And I can't believe I let you in, you left me out You left me on my own, you left me all alone I let you in, you let me out You left me scared and alone, you left me all alone I'm all alone You left me all alone I'm all alone I would've gave it all To be told I can't believe you're gone Like a dream I can't recall Now I gotta face the fact that you're never coming back Cause you're running through my dreams It's like you're on repeat Feels like eternity And I can't believe I let you in, you left me out You left me on my own, you left me all alone I let you in, you let me out You left me scared and alone, you left me all alone You used to run, run through my veins And to be honest, I know I'll never be the same I let you in, you left me out You left me on my own, you left me all alone I'm all alone You left me all alone I'm all alone I see you in my dreams, I can't believe you're gone When it's too dark to see, I'll leave the light on I'll leave the light on, I'll leave the light on When it's too dark to see I let you in, you left me out You left me on my own, you left me all alone I let you in, you let me out You left me scared and alone, you left me all alone You used to run, run through my veins And to be honest, I know I'll never be the same I let you in, you left me out You left me on my own, you left me all alone I'm all alone You left me on my own, you left me all alone I'm all alone
