I dreamed that I climbed the mountain, but I didn't climb it, so I came down and saw my old mother's hall with crooked neck. What does this portend?

Mountain climbing, spiritual goals and wishes represent sexual desire.

Halfway up the mountain, sexual fear (because of escaping sexual desire or reminding yourself not to be too indulgent)

Old mother with crooked neck, spiritual liberation and baptism represent rationality.

This nightmare with negative emotions mainly reflects your recent weakness, fatigue, fatigue and lack of qi and blood.
