Dreams dictionary: Nightmare

Dreams dictionary: Interpretation 1
To dream that you are having a Nightmare proposes that you are as a rule excessively liberal and carrying on with an existence of abundance. You have to tone it down and permit the psyche and body to rest and mend. On the other hand, the fantasy may imply that you are encountering a misfortune toward your objectives. You have to figure out how to take a negative and transform it into a positive.
Dreams dictionary: Interpretation 1
To dream that you are having a nightmare suggests that you are being overly indulgent and living a life of excess. You need to tone it down and allow the mind and body to rest and heal. Alternatively, the dream may mean that you are experiencing a setback toward your goals. You need to learn to take a negative and turn it into a positive.
Dreams dictionary: Miller Dream Interpretation
To dream of being attacked with this hideous sensation, denotes wrangling and failure in business. For a young woman, this is a dream prophetic of disappointment and unmerited slights. It may also warn the dreamer to be careful of her health, and food.
Dreams dictionary: English dream book Zedkielom (Morrison)
If you dream of a heavy nightmare, which you can not recall without a shudder of the soul, it is a sign that you are under the influence of a stupid and careless person who can ruin your life if you do not protect yourself.
