Im into lyrics, so my questions are more about them, i saw a phrasal on a text:

section off:?

for example:section off myself

Is it understood to mean to take yourself away from things or shuttin' yourself away from sth...
cmon is here nobody knows?
Section off myself
Put a wall up/What the hell have I done
Keep the dog at bay
Survive by saving me!
Values and the game
Not a fuck-up - Not a part of your lie
I am one, I am all - I'm above and beyond!
Students: Are you brave enough to let our tutors analyse your pronunciation?
"Section off myself"

To section off is to cut off, or cut up into smaller areas. For example, police will often "section off" a crime scene to make sure no-one enters.

If you "section off" yourself, it is a poetic/metaphorical way of saying that you are cutting yourself off from someone/something. I think that's what you suggested it meant, so you are correct.
