I tend to forget things

I tend to forget things. The only thing that keeps my memories alive is dreaming. During the day I listen to all that is said to me, but in the evening I already forget it. But when I fall asleep all that I learned that day tries to make it to the surface of my conciousness in some enigmatic form. I will tell you my dream. Could you remind me what I forgot about today? Otherwise someone will certainly be mad at me tomorrow.

My drawing skills are not that good, but I will try to draw you some outlines of my dream. To make sure you understand it see the description below:

The question is: Could you remind me what I forgot about today?

Credit (but also a hint):

This puzzle was inspired by (the mechanics of) this great puzzle by Ankoganit.

• @lois6b I hope you will get into my dream deep enough to see that this is not a mistake :) Commented Oct 26, 2016 at 6:57
• funny answer. "Black Brown and White" is a song of Big Bill Broonzy. Big Bill means you have forgot to pay! :) (Nice riddle!) Commented Oct 26, 2016 at 7:33
• Small progress: Click on the image, and you get a different image. Use the text in those, and you get more images... Eventually, you need a 'password' and two 'keys', whatever they are. Commented Oct 26, 2016 at 7:43
• In addition to @boboquack I assume that the passwords / keys you will be getting somehow are (partial) pointers to the next image. I think that the hint from the first picture will somehow give you the password. Would fit to cipher (@loise6b) as well... Commented Oct 26, 2016 at 9:06

I followed the riddle about the dragon and got a result of

'drAgN' (capitalised parts were described as larger and the o is the crushed 'hole').

I used a

Vigenere shift with that as a key using the order of lowercase uppercase and numbers provided by @M Oehm commented on the other answer.

This led to the following page:

https://i.sstatic.net/QHPzy.png

From there much of the labarynth is visible including the key

'd6AQ5'.

I then decrypted the door on the right at the start with that key and the key

('dream')

which I got from the hint that the key is

('what this is all about')

leading to a result of the page

From the clue

(about going to 'his or her door':)

We know

(that they forgot about going to visit someone.)

From the clues

(about the shape of the puzzle and about the watch being stuck at 5pm:)

We know

(that they forgot about having tea with someone because 5pm is tea time and the puzzle is in a 'T' shape.)

From the clues

(about it being somwhere 'near you and my ant':)

We can get the word

('aunt'(by adding 'u' to 'ant'))

Putting it all together, we can work out that they have forgotten about their plans to

have tea with their aunt.

• That's brilliant! The labyrinth continues with ZKFwX and even further. Commented Oct 26, 2016 at 19:42
• How did you get to that? Commented Oct 26, 2016 at 19:53
• The codes on floor tiles are just connections that you can enter straight away: ZKFwX, Dldtx, opkOi. Commented Oct 26, 2016 at 19:57
• I think thats the whole of the answer. Please tell me if I need more detail on what was forgotten Commented Oct 26, 2016 at 21:47
• You are almost there. There are clues about who you are supposed to meet. Filling this detail it is all the answer I expect :) Commented Oct 27, 2016 at 6:09

Partial answer

First, click on the image in the question. Hidden behind what you can actually see in the question is a quite different Stack.Imgur image:

This image contains two five-character codes. Each of these yields a Stack.Imgur image of its own:

Finally, each one of these two images leads to yet another Stack.Imgur image:

Putting together all the text from these images:

1. There is some ordering in my head. It starts with an 'a' goes through an 'A' and ends with a '9'.
2. I see a door ahead. It is decorated by a dragon carved in the wood. It is crushing a small circle and it grows bigger when I look at its middle and its tail.
3. The door ahead reminded me that the thing I forgot about was that someone wanted me to be at his or her door. Tomorrow.
4. The door has a panel with numbers and letters. But what is the correct code?
5. Door is locked with two keys. I have to find them.

From clue 1, I think we should be looking for another Stack.Imgur image with a code of the form a?A?9. Clue 2 might be telling us something about the same code (perhaps "small circle" = o?) Clue 4 could again refer to the same code, or perhaps a different one since clue 5 seems to tell us that there are two different codes.

• I think the clue in the first room means that the possible characters of imgur addresses are ordered a-zA-Z0-9; we might need that ordering when we find numerical clues. I've tried "drAgN" - a dragon that crushes its circle and whose letters at the middle and tail are capital - but that didn't work, of course. I think such literal clues hard to pull off anyway, because the author doesn't have control over the address. As far as I can see, the images have no metadata or hidden text that can be revealed with a flood fill. Commented Oct 26, 2016 at 18:52
• As to the "drAgN" thing - sometimes you don't have control, but you get lucky to get an address like this :) (or not the adress but its part) Commented Oct 27, 2016 at 6:21
• Well, now that I see how the keys work I can also see that you can have several shots: Upload both the door and its destination n times and you get n × n possible outcomes. That's clever. Commented Oct 27, 2016 at 6:27
