How did you get here? From somewhere in [CELIA - K PATH]
"You name the picture and the fog dissipates. Or at least, it dissipates - partially."
The dreamy fog continues to restrict your ability to progress. This time it has appeared in a doorway, and unless you climb the staircase to nowhere, you need to get the fog to dissipate completely to carry on. There are some backwards words written on the wall, as well a large letter written separate from the rest. Perhaps you can use these clues together to figure out the solution. Remember, when you see something that you don't recognise, it helps to search externally. Google is your friend!

“Search for the quote on the wall. You will find something that references a blue J, so to speak.”
