Do dreams come true?

I was just going to bed and when I get under the covers, get myself situated. I usually think about things as I get ready to go to sleep....like dreams, fantasies or maybe just things I would like to do and even things I need to do. I don't know if you can necessaily call them dreams but sometimes I think about special things I wish would happen.....do these ever come true?? I have to say for the most part they don't because I have thought about a certain man enough that he should be getting telepathic sex shockwaves every night or vacation that I should have sand in my bed under the sheets by now. You know they say there is power in the mind but either my mind and me thinking the things I do have a disconnect somewhere along the line because nothing ever seems to happen for me. Maybe I don't know how to achieve the dreams and thoughts I have but maybe they are just not meant to happen. I don't know but if nothing else I wish that man would have sexual shockwave from me because I sure have sexual something about him!!!!
