The synchronicities you see are going to vary a bit for everyone.
Seeing numbers like 11:11 or 222 are great signs that something is going on. For some, that might be a sign of union, for others, it could be a sign of progress to whatever stage they are on.
Names showing up repeatedly, songs that remind you of them playing at random moments, seeing their car type multiple times in a day. These patterns happen across the board. Some people get animal symbolism (like doves), others see heart shapes in random places, like coffee foam or leaves.
Spirit finds whatever language gets through to you specifically.
But I don’t think there’s any one sign that means you’re going to see reunion right away. Depending on where you are in the path, these signs can continue for years without a physical reunion actually happening. I’ve seen people get bombarded with synchronicities for literally a decade while still in separation. They’re confirming the connection is real and guidance for where you need to grow, not necessarily a countdown timer to reunion.
They can be great signs if you let them, but only if matched with actual action.
There’s no sign for “just sit on your hands and wait”.
Physical sensations in your chest area are common too. Some describe it as pressure, others as expansion or pulling. It ranges from pleasant warmth to actual pain depending on what phase you’re in. If it feels good right now, you might be in an opening stage rather than a clearing one. Either way, the intensity of signs doesn’t always correlate with how close reunion is timeline-wise.
