Dreaming that you are dreaming means your emotional state. You are excessively worried and fearful about a situation or circumstance that you are going through.

It is common to dream that you have had or are having a dream.

You could be experience a false awakening, in which you dream that you have woken up from an earlier dream, and are performing the activities you normally perform on waking, such as getting dressed and brushing your teeth.

Such a dream can be a sign that you have fallen into a rut in waking life.

You may also have a lucid dream, in which you are aware that you are dreaming while you are having the dream.

The meaning of a lucid dream will depend upon the content of the dream.

Night is related to the passive principle, the feminine and the unconscious. Hesiod gave it the name of ‘mother of the gods’, for the Greeks believed
that night and darkness preceded the creation of all things (8). Hence, night—like
water—is expressive of fertility, potentiality and germination (17); for it is an
anticipatory state in that, though not yet day, it is the promise of daylight. Within
the tradition of symbology it has the same significance as death and the colour
black.

To have a dream that takes place at night, represents some major setbacks and obstacles in achieving your goals. You are being faced with an issue that is not so clear cut. Perhaps, you should put the issues aside so you can clear your head and come back to it later. Alternatively, night may be synonymous with death, rebirth, reflection, and new beginnings.

If you are surrounded by night in your dreams, you may expect unusual oppression and hardships in business. If the night seems to be vanishing, conditions which hitherto seemed unfavorable will now grow bright, and affairs will assume prosperous phases.

Dreaming of night means some major setbacks and obstacles in achieving your goals. You may find that some issues you are facing are not all that clear and you need to put them to rest for awhile before a decision is made.

To dream that someone is being mean to you, suggests that you are being too hard on yourself. You need to give yourself a break. Alternatively, the dream may be a metaphor that you are looking for "meaning" or significance to some life issue.
