Alright, I'm not a big believer in this number theory, but I decided I'd try and make a list of the numbers and objects associated with them so that people start looking around so much.
1:
- Box under the television (Note that this is a repeated texture throughout the demo, and can also be found near the backdoor)
- The tape itself
- The fuse (I've seen people relate this back to the shape of the fuse, which I feel is a major stretch)
- Pulling the fireplace switch (This has been counted as an action by some, mainly in lists which revolve around the fuse as number 2, seeing as the switch must be pulled to reach the fuse. There is also a book atop the fireplace with a 1)
2:
- Finger (Has a 2 on the fingertip)
- Fuse (Has a 2 on it? I can't confirm this, but I've seen it thrown around a lot)
3:
- The chained cabinet (This of course requires the bolt cutters to open, and yields the tape. Three is on right side of cabinet)
- The lockpick (Has a 3 somewhere on it. A bit sketchy on this one)
- Stew (Three cockroaches escape once it is opened)
4:
- Axe (Has a 4 on the handle. Potentially multiple)
- The bloody note received after the tape (The 'u' in 'You' is resembles the number 4)
5:
- Cabinet with the finger (5 in blood to the right of the scissors)
6:
- Axe (Again, I've seen sixes on the axe thrown around frequently, but I'm not sure about it at all)
- There are six mannequins present within the demo assuming the top floor is reached
7:
- Everything was 7
- Piano (Underneath there is a 7)
- Finger (Apparently also has a 7 on the fingertip?)
- Mirror (From an angle to the right of the mirror a 7 can be seen on the left side of the mirror in an almost reddish tint)
The most logical progression I could find was (Assuming all necessary steps are taken to get these items):
- Fireplace switch (Simple. Hit the switch before the VHS tape to get the fuse)
- Fuse (Plug in the fuse to get access to the third floor)
- Chained cabinet (Get the bolt cutters and get the VHS tape)
- Bloody note (Watch the tape and be sure to trigger the axe)
- Cabinet with finger (Go to the cabinet and grab the finger)
- Axe (Actually go get the axe)
- Piano (Hit the piano)
I've seen the idea of finding the missing mannequin thrown around a lot (Considering only six are present and we know everything in the demo is 7), but I think what we are going through actually is to find the last mannequin. If we go to the bottom floor we see the voodoo dolls which are at three different elevations of height (Representing the three floors of the home). One is on the bottom elevation, this of course being the mannequin that was tossed. There are four on the middle elevation, as there are on the second floor. Finally we have two on the top elevation. One of these is found in the phone room and the other is a mystery. I feel it's a given to assume that the final mannequin is found in the glitched room located on the top floor. So I don't think it's safe to say our goal is to find this mannequin to progress further in the demo.
