The World of Dreams

Not to be confused with Mario's Dream.

The World of Dreams is an anomalous area found in some personalized copies of Super Mario 64. It takes the appearance of a large area with several parts of a castle-like building being scattered around, and strangely, several paintings of Princess Peach have been reported to be scattered around the vicinity of the area. It's access point is inconsistent, though some have reported the area to replace the castle courtyard, or being accessible by jumping into a Princess Peach painting.

Geography
The World of Dreams is described as a large grassy or sky area filled with several assets from Princess Peach's Castle, mainly simply being inaccessible structures dotted around the area, or pillars and similar random objects that can be used to explore the level. This area is known for the strange, flat walls scattered around the area with a painting of Princess Peach on them that appear to go unexplained. No stars have been reported in this area, though a strange segment known as The Pathway has been reported to appear by reaching some top point of the area, commonly through the use of the Wing Cap.

The Pathway
The Pathway is reportedly a large dark area with a long path going through it with several of the strange Princess Peach structures dotted around it. The path usually does not lead to anything, making it's purpose a mystery, though some have reported it can lead to a course or a key to a castle floor.

Theorizing
Some have theorized that the World of Dreams is meant to represent the human's subconscious. If a human brain is simulated via Wet-Dry World, the World of Dreams may simulate dreams due to the level's strange and abstract nature, with the Pathway potentially representing a nightmare due to it's dark and empty appearance. This appears to apply to the darker theories related to the personalization A.I.

Others have theorized that the World of Dreams is simply meant to represent Mario's subconscious, which could explain the several Princess Peach paintings while maintaining the previous theory's explanation of the mysterious nature of the area. The Pathway could represent Mario's fears of something happening to Princess Peach, due to the dark appearance and several Princess Peach paintings, and facing his fears and walking down the path would allow Mario to obtain whatever is at the end of the path.

wasteofblood's Documentation
The Youtuber known as wasteofblood uploaded a video titled 1995/07/29 OST - World of Dreams, which appears to feature the same soundtrack that wasteofblood ripped from Bob's copy and was featured in Bob's lost video "Dreams". After being questioned about their experience with the location, wasteofblood replied that it was very similar to Bob's documentation, with some distinct differences:


 * 1) The World of Dreams replaced the castle courtyard.
 * 2) Two courses can be accessed in the World of Dreams, including Big Boo's Haunted Forest and a level called "Rainy Sky Spires", which is yet to be documented.
 * 3) The Pathway can reportedly only be found at night or during a thunder storm and leads to Big Boo's Haunted Forest.
 * 4) "Rainy Sky Spires" can be accessed by using the wing cap to fly high enough into the sky during a thunder storm or rain.
 * 5) It has been reported that the weather and the time of day can sometimes randomly change while being in the area. Because the weather and the time of day will reset after leaving the area, these changes will not carry over to other locations.
 * 6) When it's night, Boos will appear all around the area. Defeating every Boo would reportedly reward the player with a power star.
 * 7) All of the doors in the World of Dreams can be used, however most won't give the player access to a new location and instead result in the player finding themselves right in front of the door they just entered.
 * 8) All around the area signs can be found, which feature texts that ponder on the nature of dreams and equate them to doors to other worlds.
