Through the Portal's Whispers

"Confusion is the first step on the way to clarity. Or was it the second?"

To enter the room of level eleven, follow these steps:

1. Face south at a precise angle of 67.5 degrees.
2. Whisper the phrase "The nocturnal piano dances in shadows" thrice.
3. Walk 37 intentional steps without avoiding the uneven stones.
4. Pull the third curtain on the left, regardless of its color or pattern.
5. Stand still for an indescript duration between 3 minutes and 17 seconds to 4 minutes and 3 seconds.

        Remember, when the clock strikes 14, silence is your best ally.
        Invisible currents guide your path, as do the unnoted signs.
    

For successful navigation through the corridor's vibration, keep in mind the unspoken codes written between the pages of forgotten tomes. However, for truly immersive experience consider aligning yourself with the orbit of the invisible lunar being.
