So make things short,
I went into an LD after using the WBTB technique and became spontaneously lucid.
The problem is, I'm in some kind of a temple, a very, very dark temple.
I was trying to stabilize my dream by looking that the floor reflected by moon light, which then I ended up seeing everything in greyscale and slowly getting darker till I wake up.
Is there any ways to stabilize your dream without looking at things?
