Life is an illusion, a dream of sorts.
All matter is merely energy condensed to a slow vibration,
we are all one consciousness experiencing itself subjectively,
there is no such thing as death,
and we are the imagination of ourselves.

The syncs are any of your other "yous" & the "holodeck" meeting "you" at an intersection point in your life line path and/or the result of your manifesting capability within the illusion.

When syncs happen, pay deeper attention.
"You" are giving "you" a message from another life before/after the one "you" are experiencing NOW; and whatever it is is so important is one of the things that made one of the others came back, to tell you and stir/change/advise for you to take a better/more loving approach & decision.
