A dream about a girl hanging out with me but it wasnt wat it seemed?

i had a dream that i was hanging out with a girl that i knew, it was very platonic , but she asked to hang out again at the same spot, so in the dream i went there the next day and couldnt find her, i asked her friend, and she said "i asked her to hang out with you because i felt sorry for you" in the dream i laughed and walked away, but i felt sad dissapointed, what can this mean?
