Happiness Is a Warm Gun

Woke up with a song from Across the Universe going through my head... over and over... I always believe these types of moments are significant in someway, like dreams.

Happiness Is a Warm Gun - The Beatles as sung by Joe Anderson with Salma Hayek

She's not a girl who misses much
Do do do do do do- oh yeah
She's well acquainted with the touch of the velvet hand
Like a lizard on a window pane

The man in the crowd with the multi-colored mirrors
On his hobnail boots
Lying with his eyes while his hands are busy
Working overtime
A soap impression of his wife which he ate
And donated to the National Trust

I need a fix 'cause I'm going down
Down to the bits that I left uptown
I need a fix 'cause I'm going down
Mother Superior jumped the gun
Mother Superior jumped the gun
Mother Superior jumped the gun
Mother Superior jumped the gun
Mother Superior jumped the gun
Mother Superior jumped the gun

Happiness is a warm gun
( bang bang shoot shoot )
Happiness is a warm gun, yes it is
(bang bang shoot shoot)
When I hold you in my arms (oh yes)
When I feel my finger on your trigger (oh yes)
Don't ya know that nobody can do me no harm
Because happiness is a warm gun, momma
Happiness is a warm gun
-Yes it is.
Happiness is a warm, yes it is...
Gun!
Well don't ya know that happiness is a warm gun, momma? (yeah)

I have a vague sense of possible meanings, but not enough to go into at depth, or even at surface at this point.
