And looked within, and fainted straight... the horrid sight to see...
"You know you're not supposed to go in there. What is your fascination with my forbidden closet of mystery?"
— Chief Wiggum, The Simpsons
You've heard of the Forbidden Zone. Here's its Lighter and Softer counterpart.
The existence of a room that is forbidden to everyone else. There is usually no specific explanation: all characters are told is that they must avoid it. This can lead to characters seeking it out because it's a Forbidden Fruit. The reasons for its secrecy vary — maybe the room belonged to someone they once loved, who is now deceased. Maybe the room represents a painful part of their life for them. Or maybe it's sealed off for sinister reasons.
Usually, finding out the secret behind it may change the character's perception of the homeowner for better or for worse.
A forbidden room is often kept locked, and the protagonist might try to find where the key is hidden, or enter through the window. If they accidentally find the key, they are then almost certain to explore the forbidden area.
Can be Truth in Television, in that some houses have a sitting room which is only used on very special occasions, a study which only one person is allowed to enter, or a room which is forbidden to children because dangerous or inappropriate materials are kept there. An attic or basement is often an area off-limits to children.
Differences this trope has from Forbidden Zone:
- Forbidden Zones are often deadly, hence them being called "forbidden zones". These ones are sealed because of some sort of emotional value to another character.
- Characters may be sent to the Forbidden Zone as consequence. These types of rooms aren't meant to host anyone else.
- Usually, these rooms hide some sort of dark secret.
If the house belongs to a woman's new husband or boyfriend, this may be a clue that he is The Bluebeard.
Also, this often is an Inevitably Broken Rule; the plot demands going to the forbidden spots eventually.

However, Alan started to kick her out of the house for long stretches of time, forcing her to sit outside and watch said cars go by.
