It's a lot of fun to decode what your dreams mean about what's going on in your mind. But they can also say a lot about what's going on in your body. Your sleep quality, diet, and other aspects of your health can affect your dreams, which gives a whole new meaning to the concept of dream interpretation.
There are a few particular dream patterns you should be aware of because they could point toward sleep problems. Other signs of a sleep disorder include constant foggy-headedness, inability to sleep in new places, constant waking up at night, and sleeping for less than four hours a night. These problems are important to treat, because when you can't sleep, you can't think, and when you can't think, you can't do anything to the best of your ability. Sleep deprivation can lead to a weakened immune system, overeating, impaired memory, indecisiveness, breakouts, and a lot of other awful things.
While interpreting the content of dreams is very individual and not entirely scientific, specific dream patterns have been proven to reflect certain sleep difficulties across the board. Here are some dream abnormalities that could potentially point toward health issues. They alone don't prove you have one of these problems, but they are worth bringing up with a doctor if you've been having trouble sleeping.
