Having vernal dreams during menstruation is a normal physiological reaction. During menstruation, the estrogen level in the body drops to the lowest level, while the androgen level related to sexual desire does not change significantly and is relatively high, therefore, it is normal for erotic dreams to occur during menstruation. In addition, if you are stimulated by sexual content during the day, it can also lead to nighttime aphrodisiac dreams. In short, it is normal to have vaginal dreams during menstruation, but it should be noted that women’s resistance is relatively poor during this period, so they must pay attention to keeping their vulva clean and hygienic, change their sanitary products regularly, and preferably do not have sex.
