LUKE: "Still...there's something familiar about this place. I feel like...I don't know..."
STRANGE VOICE: "Feel like what?"
LUKE: "(looking at the creature) Like we're being watched!"

YODA: "...This one a long time have I watched...
Being watched by Yoda is a familiar felling for Luke.
It has been going on a long time.
😛
He is in the presence of another Force-user - Ben has already begun his Jedi training, he is aware of such things now.
It's that simple really...
from the evidence of in the prequels Ani could only see the future when it involved the death of his wife & mother.
eg traumatic events to people close to him.
Luke had a traumatic vision while Han was tortured on Bespin, but that was in (real time).
the point i'm making is that Anakin didn't see random visions of places he would go to in the future (according to prequels) so I must assume that Luke didn't either.
