I've told my kids that I'll come back from the dead and haunt them if they put me in a nursing home.

2. Reappearing or regaining popularity after a period of absence or decline. I haven't seen her in years, and now she's suddenly back from the dead, so she must want something. I bought bell-bottoms because '70s fashions are coming back from the dead. The electric piano is back from the dead, huh? It's not just relegated to soft rock ballads anymore.
