Delirium

I can see visions so far away
Day by day pictures appear to me
I know it's all because of my mind
There's something wrong in there when I find
That I'm in time of trouble
I drink it all away

Have a try come down to me one night
Look and find drink and you'll be so kind
To be the better one in my way
You have to drink yourself like I say
You'll gonna see then wonderful things and
You want me to stay

I gotta go on 'cause I need it so i need it
So badly

One fine day i saw a plane around
In my mind also were purple lights

To be the better one in my way
You have to drink yourself like I say
You'll gonna see then wonderful things and
You want me to stay
