Dreaming of Ghosts

I saw many weird white and black ghosts in my dream, yesterday night. It was pretty scary and unusual feeling when I woke up from the dream.

I searched a lot on internet that whether it signifies anything or not. According to my findings (I don't know how authentic, these websites and their interpretations are!), seeing a ghost in your dreams can signify something that is gone but can not be forgotten, or something, which is almost forgotten but can not be released from my thoughts. Ghosts, in dreams, also signify some shadowy worries and anxieties about life, which I might have to think, consider and resolve soon.

Apart from all this, what additional information I found was that if you see some deceased relative or known person's ghost in your dreams, it generally signifies some unresolved issues. In these cases, you need to pay certain attention towards your surroundings and environment, if there is any presence of some other characters around, and any odd aspects of the apparition, if happening. Ghost dreams can lead to various meanings, out of which two are explained below:

Interpretation based on Psychology:

The shady ghosts of your dream usually signify those aspects of our lives, which we are afraid of and dread in the darkest of our thoughts. Those aspects may not be frightening, but our fear for them makes them more dreary and intolerable. Once you start exposing these dark dreadful energies to the daylight, you will find that it is just one side of a coin that has turned into a nightmares and that is just the fear, otherwise the thing is almost unintelligible. You have to acknowledge that your psyche is constituted of many different forces and you need to accept them all in their valid formats to have balance in your life.

Dreaming of ghosts may also signify your fear for your own death. According to Sigmund Freud a ghost was a symbol of the mother.
 
Interpretation based on Occult:

According to the mystics, watching ghosts in dreams may signify certain dark forces and energies that reside within ourselves, and are either unknown to us, or are known but not entirely acceptable to us. However, ghosts may also consider you as a medium to convey certain messages. In these cases, most of the times we see the ghost or spirit of people we used to care about, when they were alive.
