Hey there, Masoud
Now you are taking advantage of my good will.
You can bet I'll ask you about it.
I believe you are talking one of Fagner's songs called Me Leve (Cantiga para Não Morrer)
which was performed on the album A Mesma Pessoa
You were right!
"Me leve" is an example of Imperative.
"Possa" is an example of Subjunctive.
You should take a look on these posts:
Se acaso você não possa
= In case you may / could
Me carregar pela mão = Hold me by the hand
Menina branca de neve, = Snow-white girl,
Me leve no coração. = Remember me though / Take me to your heart.
