How To Disappear Completely lyrics

That there
That's not me
I go
Where I please
I walk through walls
I float down the Liffey
I'm not here
This isn't happening
I'm not here
I'm not here

In a little while
I'll be gone
The moment's already passed
Yeah it's gone
And I'm not here
This isn't happening
I'm not here
I'm not here

Strobe lights and blown speakers
Fireworks and hurricanes
I'm not here
This isn't happening
I'm not here
I'm not here
