The stars are very special because they are a reflection of ourselves, a reflection of infinity so naturally we would feel at home when looking at the stars because we are made of stars. The feeling you had of bliss and euphoria will come and go, it’s the eb and flow of life. We have the positive side and the negative side, we enter into those blissful states because our mind sees it as possible to enter into those states by raising our vibrations. We can do this anytime really most just either are blocked energetically or their thoughts are in a different perception of time. The awakening isn’t always positive, it’s the ego death of the old soul to be reborn into the evolved consciousness of the future. There is going to be ups and downs regardless because it is the revealing of all that is hidden within yourself. However the more you question the ego, the more that is revealed to you through the veil. The spirit world and hte material world are interconnected and linked therefore it is not hard to tap into that current once you develop access to it. Once you open the door you can never go back, because the memories are always there, the imprint is never forgotten.
hope this helps!
