I had a dream that the name of the girl I have a crush on at work is named "Macey" or "Macy" and her nickname is "mouse."

I thought this was very strange and I often have random dreams about names. For instance two nights ago I had a dream and all it was, was the name "Alejandra." I mean I've never even met an Alejandra before. I even had to look it up to make sure it was a real name. haha

Any insights?
