Dream about a random guy I’ve never seen before ..

I had a dream a while ago where I was flirting /dating this cute random guy and dude he was sweet as hell and I wish he was real . This was after ranting about a guy I like to my best friend and how we’ve been talking for months and he still has no interest in me and I mentioned how I wished there was a guy who cared ... Did thinking about a sweet guy cause that dream or what does it mean???
