Like Yume Nikki and many of its fangames, there are a variety of events that Soutarou can come across in Mikan Muzou. This article contains a list of many of the events found throughout the game, along with their individual locations, their requirements to activate, and what consequences activating them may have.
Bored
Location: Soutarou's Real Room.
Effect Needed: None.
Required Sanity: Any.
Description: In the real room, if you wait a little, Soutarou will yawn. Every time Soutarou yawns, his level of sanity will randomly increase/decrease by 1 point.
Waking Up
Location: Various locations.
Effect Needed: Any/None.
Required Sanity: Any.
Description: Most of the effects have a unique waking up action. For example, if you have the Tape effect equipped, Soutarou looks like he is being taped until he disappears; if he's in the child state of the Down Jacket effect, he'll fall on his knees; or if he uses the Corpse effect, he will disappear and leave behind a blood puddle.
What's also interesting is that the only time Soutarou will pinch his cheek like any other dreamer is when he has the Black Hair effect equipped.
Trying to wake up when he's already awake will result in him looking up - probably at the player - confused.
Nature of Chasers
Location: Various locations.
Effect Needed: Brass Knuckles.
Required Sanity: Any.
Description: In this game, Shokushu as chasers work differently than in other fan games. If Soutarou attacks a calm Shokushu while wearing a bag on his head with the Brass Knuckles effect, it will be killed. However, if Soutarou does the same action without the bag on his head, the chaser will become enraged. If Sautarou is caught while they are in this state, he will be transported to an inescapable area.
Hazy Memory
Location: Soutarou's Dream Room.
Effect Needed: None.
Required Sanity: Any.
Description:Please note that you won't be able to witness this event if you have collected all effects.
In the dream room, keep waiting until you hear an alarm sound. Then, check the drawer next to you; a short cutscene will begin, showing with that appears to be some kind of fetus. The sound of a cardiometer can be heard in the background as well. Pressing any key will make Soutarou come back from the "trance" laying on the ground.
Viewing this event highly decreases your Sanity Level.
Black Stone World's Ghosts
Location: Black Stone World.

Manor Shenanigans

Effect Needed: Brass Knuckles/Picture Frame.
Required Sanity: Any.
Description: Somewhere in the Rainwater World's sewers is a brown sliding door that is entrance to a manor, where dozens of housemaids will bow down before Soutarou everytime he enters a hallway or a room, except when you've equipped a certain effect. If Soutarou wears the Brass Knuckles before them, they will look down on him, before forcing him to unequip it.
In the room that's home to the Picture Frame effect, using the latter will result in the original frame being fractured as well.
The Manor's Secret
Location: Maid Mansion.
Effect Needed: None.
Required Sanity: Any.
Description: In that same manor, there is a room with a moveable object who's blocking a secret room. At the end of it, there is a view of what could be a bloodied scenery. When quitting this place, Soutarou will first look at that scenery one more time, before coming back to the actual manor.
However, there are odds that, when entering and going at the end of the room, Soutarou will have a pained expression on his face and fall on his knees, before waking up.
Gray Buildings Shenanigans

Effect Needed: None.
Required Sanity: Any.

White Building
Location: Old Arcade.
Effect Needed: None.
Required Sanity: Any.
Description: In the arcade, interact with the machine that has a white screen to trigger a little cutscene, showing what seems to be either a church or a hospital.
