The song Delusion is performed by Suicide Commando .
it's like a maggot
digging in a rotten brain
it's like a leech
s*ck my blood
demented serpents
coming to infact the brain
return my mind
return my brain
I see black demons
trying to disrupt my mind
mental disturbance
I feel no pain
severe dementia
realize it's my decay
delusive moment
delusive mind
