If you dream or have a vision that you are menstruating, it tells you that you are letting go of pent-up tension and worry. It also represents the end of a difficult period, and the beginning of relaxation and peace in your life. Another explanation is that you deny, ignore your feminine side, don't want to listen to your feminine energy that is not in balance and thus you run into problems.
To have in your dream or vision where you are trying to stop your period tells you that you are not letting the letting go, the tensions, emotions or the end take its course by controlling it.
An alternative explanation is that there can be awareness towards the transition and/or a transformation to something new in your life and/or even a soul affirmation towards transforming changes and/or desires.
Menstrual dreams have nothing to do with being male or female it is purely about the masculine and feminine energy regardless of your appearance and/or your desires (your desired appearance). So as a man you can also dream about having your period without feeling comfortable (soul desires) + this is more than normal, it can of course be a signal but does not have to. Listen carefully to your feeling, intuition.
Dreams or visions of sanitary towels are about the cycle of life, the end and the beginning of a situation. Another explanation is that you let go of the pent-up tension and worry of a period when you needed protection, but you may have experienced this as a burden. Another explanation is that a period in your life has not gone well or has been uncomfortable.
