What does "i need you like water in my lungs" mean?

Question

ive heard it alot i just never quite understood it O.O

Answer 1

its like saying " I need you like a hole in my head". it means they really really don't need you.

Answer 2

You don't need water in your lungs, so this probably means that they don't need you, I guess.

Answer 3

People don't need water in their lungs, so I would assume this would mean they don't need you.  Or whomever they were referring to.

Answer 4

Drink more waters then hardly salts on language before meal

Answer 5

it means that i really do not need you. water is not supposed to be in the lungs, air should be so saying i need you like water in my lungs is quite the opposite of needing.  

Answer 6

its like the well known saying - i need you like a hole in the head.

You really don't need water in your lungs, so you really don't need that person,

Answer 7

a round about way of saying, you are not needed
