When I found that I was a prisoner a sort of wild feeling came over me. I rushed up and down the stairs, trying every door and peering out of every window I could find; but after a little the conviction of my helplessness overpowered all other feelings. When I look back after a few hours I think I must have been mad for the time, for I behaved much as a rat does in a trap.

– Bram Stoker

Dracula, Chapter 3. Jonathan is hit with the realization that Count Dracula is keeping him prisoner in the castle and there is no way out for him. For a time he was overcome by a madness, like a rat in a trap.
