This was my experience as well. The ceremony would have been 6AM my time, and I would have already been at work. I set the intention to wake in the night and send energy multiple times. I woke at 1:11 and 2:22, and grounded Source energy. I was also guided to send "arrows of Light" through the sky and have them land around the site in the shape of a circle and a heart. After the second meditation, I felt a movement in the heart of Earth. Like a baby in womb moving. I also saw light flashing rapidly in my third eye. At that point I knew I did not need to wake for a third meditation; whatever was going on was already in motion.The day of the ceremony I already sensed everything had changed in my area before the indicated time.
Perhaps I already felt this from the start? From the moment I heard of the activation I did my ceremonies out of time and just said that the energy would be present on the time the box needed it.
For me the change happened between 3 and 10 hours earlier (when I was asleep) than the time stated but that was also the reason I did it all out of time.
