Is it possible for dreams to create a foundation for idealisation? 

To put into context, I had a dream a few months ago about this girl in my class and afterwards I became obsessed with this dream and wanted to ask her to be my friend. She’s pretty popular and she’s on social media quite a bit and so I decided to look her up and follow her. 

When I’d tell myself it was just my head needing someone or something to fill my boredom I stopped looking as much, but then I had the same exact dream again instantly fell back into the idealisation. It was so weird. I’ve had “regular” idealisations of people before but this was something completely new and honestly quite strange (even for me). I’m over it now but I thought it was quite interesting to think about how my brain took a completely imaginary scenario and got a massive high off it. I know pwBPD often create scenarios in their heads but does it happen when unconscious as well?
