If you are not angry, I will talk about it.
Dreams are generally modified by the superego (that is, they are not allowed to happen in real life), that is, your real life, or what you desire, will appear in your dreams as a very metaphorical thing!
Note: dreams have a lot to do with sex! (human instinctive tendency)
And your dream is a dream that many women will dream. Your dream is almost unmodified, which is a very direct expression.
It's just that you're tired of menstruation, a female-specific cycle, or worried about masturbation!
