Conceited, like an out-of-body experience? (5,7)

I believe the answer is:

above oneself

'conceited' is the definition.
(as in having ideas above oneself)

'an out-of-body experience?' is the wordplay.
I cannot really understand how this works, but
'an' could be 'one' and 'one' is present in the answer.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...

'like' acts as a link.

(Another definition for above oneself that I've seen is " Conceited".)

I've seen this clue in The Guardian.
