Lyrics:

They came at night, they all arrived
In form familiar to the eye
Uh-oh, uh-oh
Beware of darkness

They came at night, and patiently
They waited there to steal the seed
Uh-oh, uh-oh
Beware of darkness

Invasion, the voice behind your eyes
Invasion, intruders from the sky
They strike when you're alone

The moment came, they changed their shape
They made their move on the human race
Uh-oh, uh-oh
Beware of darkness

They came at night, the spinal tap
They disappeared and closed the gap
Uh-oh, uh-oh
Beware of darkness

Invasion, the voice behind your eyes
Invasion, intruders from the sky
They strike when you're alone

They came at night but wouldn't go
The only trace a greenish glow
Uh-oh, uh-oh
Beware of darkness

They came at night, they came to stay
Inside your mind by the break of day
Uh-oh, uh-oh
Beware of darkness

Invasion, the voice behind your eyes
Invasion, intruders from the sky
They strike when you're alone
