I think your dream is mirroring what we have been discussing on all these forums. The integration of your male/female aspects into one unified WHOLE Elly!
The 'birth of something new' symbolism is backed up twice. Once by the egg cartons (blue and pink representing the male/female duality) and the second time by Christmas - Christmas is almost always a representation of Birth because of the birth of Jesus - so birth and Rejoicing! Festivities.
I, personally, feel that you are now embarking on a new path. You should nurture these new beginnings (plucking the abundant fruit of the Tree of Life) so that you will grow into your full and Whole Self.
The fact that there SEEMED to be 'obstacles' at the top of the escalator (you are right - excellent symbolism! You are moving up into your Higher Self/Consciousness! yay!) but that they moved and you walked right by them is fantastic! The Obstacles are dissolving Elly!
A wonderful, positive dream all round....keep it up!
