How to disappear completely

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.
