Zombieing is when someone who ghosted you suddenly reappears and acts as if they never disappeared.
Zombieing is when a person who once cut off all contact, or ghosted you, comes back out of nowhere and starts messaging again as if nothing ever happened between you.
It usually begins with a casual, low-stakes text such as a simple hey or a quick reply to an old story. The person offers no explanation for vanishing and seems to expect things to pick up right where they abruptly left off.
The name fits because a connection you thought was dead suddenly appears to rise again. It is closely related to breadcrumbing, since the renewed contact is often low effort and may well go quiet a second time.
A returning ghost owes you a real explanation, not just a friendly wave. Before re-engaging at all, it is completely fair to ask why they disappeared and whether anything in their life or habits has actually changed.
