Can I talk to my subconscious with Lucid Dreaming?

[Purple Panda]

Life hasnt' been doing too well, I can't go on vacation like I'd prefer to. I've finally starting to have frequent lucid dreams now although I'm more of following the flow. I was wondering, can lucid dreams really feel like days have passed? Or does it feel like however long it is. I mean to say, if I sleep for 3 hours will it in the dream be 3 hours? Or if I'm into it enough can literally days pass in my dream at a "normal rate". (Like in dream 1 hour feels like a full day.) I've been really wanting to have a lucid dream of me walking through a calm forest just intaking the scenery without any thoughts besides the chirping birds or flowing river. If I do get this far how long will it last? I'd hate to be calm in there and then end up waking up abruptly to my alarm clock. Also, to the main question, conscious and subconscious are different but I was wondering if in my dreams I can talk to it? It would be nice to talk to someone else about my problems that are experiencing it and who better than myself?
