Islamic Interpretation of Dreams (Ibn-i Sirin):

(Atheism; Ignorance; Night; Obscurity) In a dream, darkness means straying from God’s path, being lost, committing an error, erring, confusion and perplexity.

If one walks out of darkness into light in his dream, it means salvation, safety, guidance, repentance from sin or release from prison. Darkness in a dream also represents an oppressor.

Thus, walking into a dark place in a dream means being unjust. Obscurity in a dream means the darkness of one’s heart or blindness.

It also could mean loneliness, keeping to oneself or hiding from people.
