In movies I grant youth, when in Rome I grant a wish.

I hold what’s worn and quietly wait, Yet I can slow you down by holding on. A basket of pauses, a verb of delay What am I?

Three letters make up my name, I twist, I slide and slither all the same. In rivers or oceans I wriggle with ease, What am I that moves as I please?

They call me mellow Living in a submarine But I'm not scared When I follow the brick road.

Everyone has one, but not everyone gets theirs. It’s often found at night, but can be troublesome during the day. It can inspire or scare.
