February 12 at 2 a.m. on the third day of the first lunar month.
When I woke up, I remembered that when I was playing the Rubik's Cube, I could rotate all sides very freely, as if those rotation tracks were very clear, as if I had a good brain image function.
In reality, my brain image function is very weak, and I can't see any images when I close my eyes. ）
In the past two days, I began to challenge the yellow face up to spell the white cross, and the success rate was much higher.
I feel that the rules are much clearer, and when the white block moves in different target directions, the originally very vague trajectory slowly surfaces.
For example, the "psychological characteristics" written in the book "Deliberate Practice" are gradually forming.
Especially the two or three twists that I sat in the quilt before going to bed last night, and it seems to have gotten better all of a sudden.
Maybe it's this that causes you to fall asleep!
After writing the above, I couldn't help but be curious about the dream, and took the bedside Rubik's Cube and twisted it twice, and each time I could successfully spell it into a white cross, it was really like in a dream, and the original chaotic trajectory seemed to be able to see through it at a glance. To be precise, you should be able to feel the four-color white block moving that way.
It's so interesting! 
February 13 (the third day of the Lunar New Year).
I woke up in a dream of twisting the Rubik's Cube again.
It seems that what is going to be explored, and practicing it again with a pleasant state of mind before going to bed is conducive to the subconscious mind to continue processing.
Grabbed the Rubik's Cube at the head of the bed and twisted two more CFP white crosses, each of which was correct.
It's just that it's not particularly fast.
I didn't expect that after such a short period of time, a psychological characteristic was quickly established in the brain, and I felt that it was more appropriate to call it a mental image.
