Sirens (1993)

Giddy: ...did you know it could be dangerous to wake somebody up when they're dreaming, well, because you leave part of your brain behind. And if it happens too many times, you go feeble in the head.
Sheela: Yeah. You're living proof.

Sheela: One day we're gonna tickle you. And we're gonna keep tickling you all over. He will also be tickling you.
Giddy: He will not.
Sheela: Look at, look at her goosebumps, you can she she's ticklish.
Giddy: My giblets are free for the whole world to see.
