You might try something like this:
INT. BEDROOM - NIGHT
CHARACTER lays in bed, asleep, but not soundly. He tosses and turns.
INT. BOARDROOM - DAY (DREAM)
Character stands, confronting ANTAGONIST across the boardroom table.
CHARACTER
You can't force this policy down the Board's throat! I'll stop you!
ANTAGONIST
And who's going to help you? Everyone else here has too much to lose!
INT. BEDROOM - NIGHT
Character thrashes, talking out loud while still asleep.
CHARACTER
You won't win! I won't let you!
This, of course, is a suggestion. There are more than likely dozens of ways to do it; this just seems to me to be the quickest and easiest.
Cheers!
