Absolutely not! This is a great indicator, sign, etc, whatever you want it to be! Things only mean something if you give them meaning!

So, If I was blessed with an amazing dream like this, take it and bask in it! Your subconscious works so hard at night and that is the time it is making magic happen! SO take this as an awesome thing. The only reason you woke up sad was because you were focusing on current reality instead of the reality in your mind, which is the real reality. I just heard a video this morning from Abe that said we are actually MOST in alignment right when we first wake up! Which totally shocked me because sometimes when I first wake up  I feel most out of alignment! But I really liked the idea of thinking I can be most in alignment the first thing in the morning. So work for a little bit to get most in alignment first thing in the morning and then lay in bed for 5 mins or so and just bask in it like Abe says! Don't doubt when the universe brings you awesome things/dreams like this! Take it and run with it <3
