What does it mean to dream of a flood?

I just want to tell you the scientific explanation of dreaming about floods. All water-related dreams are caused by excessive urine accumulation in the bladder or bare abdomen and cold back. If you dream this kind of anxious, sad and sad dream for a long time, your liver will have problems. If you dream of fear for a long time, it is a heart problem. I think you are a dreamer. You don't get enough sleep. Paying attention to a static thing for a long time during the day is easy to get bored and a little anxious. Uh ~ I need to improve my sleep
