Mistakes and misunderstandings are great for this. Say, a person goes to a pet store to buy a goldfish but comes back with a hamster because they misheard the shopkeeper. Then they try to put the hamster in a fishbowl. The confusion and the wrong actions are both strange and funny.
Surprise elements often do. For example, when a normal situation suddenly takes a completely unexpected turn. Like a librarian who starts break - dancing in the middle of the library. It's so out of place that it's both weird and funny.
Absurd characters can also make a story weird and funny. Imagine a superhero who is afraid of mice. This kind of character goes against the norm and creates a really strange yet humorous situation. They do things that are not expected from their supposed 'type' which makes the story interesting.
Surreal characters can make a bedtime story both weird and funny. For example, a talking teapot that has adventures with a flying spoon. The idea of inanimate objects having conversations and going on quests is not normal, which makes it weird, but also hilarious. Another element is unexpected situations. Like a princess who doesn't want to be rescued but instead wants to rescue the dragon. It goes against the traditional fairy - tale norms and thus creates a funny and strange story.
Mixing different genres can create a weird and funny bedtime story. For example, combining a fairy tale with a detective story. So you might have Cinderella trying to solve a mystery at the ball. Absurd situations are key too. Imagine if all the beds in the world started floating one night. And the use of wordplay can be great. If a character's name is something like 'Sir Laughsalot' and he does things that are really comical because of his name, it adds to the overall weird and funny feel of the bedtime story.
Character traits are important. A really superstitious character can make a story both creepy and funny. They might see signs of a 'curse' everywhere, like when the lights flicker and they think it's a ghost, but it's just an old electrical system. Their over - the - top superstitions create the creepy atmosphere at first, but then as the real reasons are revealed, it becomes funny. Also, when characters are in a situation where they are trying to be brave in the face of something they think is scary but are actually really clumsy or make stupid mistakes, it adds to the both the creepiness and the humor.
One element is unexpected behavior. For example, if a timid character suddenly becomes super brave and does something wild in a comical way. Like a shy librarian who stands up to a group of rowdy patrons by using really big words in a sarcastic tone. It's funny because it's out of character and badass because they're standing up for themselves.
Exaggeration also plays a role. If a character is overly paranoid about every little sound in an old mansion thinking it's a ghost, and then the 'ghost' turns out to be a mouse that makes really loud noises. The extreme overreaction of the character to a normal situation is both scary in the moment and funny when the truth is known.
Surprise can be a key element. For example, if you expect a scary monster but it turns out to be something harmless and silly like a bunny with big teeth painted on it. Another element is the contrast between the situation and the reaction. If someone is in a supposedly haunted place but they respond in a really nonchalant and comical way, like singing a happy song while walking through a 'haunted' corridor. It creates a sense of both creepiness and humor.
Surprise elements can make a story both funny and disturbing. For example, if in a story, a character who seems very proper suddenly starts doing something completely out of character like dancing on the street in a crazy way while wearing a ridiculous costume. It's funny because it's unexpected, but it can also be a bit disturbing as it breaks the normal perception of that character.
One important element is misfortune. A story where someone has a series of small unlucky events that seem to pile up can be both funny and tragic. For instance, a person is running late for an interview. First, their alarm doesn't go off, then they spill coffee on their clothes, and finally, they get a flat tire. We might chuckle at the chain of bad luck, but it's tragic for the person who is trying to make it to the interview. Also, irony plays a role. A person who is always preaching about safety but is the first one to get into an accident due to their own carelessness can create such a story.
Surprise is a big element. For example, if a character is expecting a ghost but it turns out to be a prankster friend in a white sheet. Another element is the use of over - the - top reactions. If a person screams like crazy at a little mouse thinking it's a monster, that's both scary (for the person in the story) and funny for the reader. Also, the setting can contribute. A spooky old castle that has a bunch of goofy - looking bats flying around can be both scary and funny.
Surprise elements. For example, if someone is walking on a tightrope between two rooftops thinking they are skilled enough, but then a pigeon scares them and they start wobbling all over the place. The unexpected presence of the pigeon makes it crazy dangerous as they could fall, and also funny because of their panicked reaction.
