Does dreams make sense?

I've watched on t.v that a monk had dreamt that Lama told him a lady will come to monastery and will request him let her with them when this was only for monks though he going to let her with them and teach Dhamma. Next day it happens what he had dreamt about; first he disagreed but later on he remembered his dream last night he had and then she became nun. So does dreams making sense ? I had one on full moon day that I'm crying next Buddha's statue in vihara saying give me power and peace.
