Dreams are different: pleasant, joyful, scary, bright. In a dream, we may feel uncomfortable: too disgusted or very scared. Many people feel uneasy, for example, from seeing a homeless person in a dream.
A homeless person may be unkempt, dirty, show aggression, and perhaps show pity and compassion. In any case, the appearance of a homeless person in a dream carries an important omen. Be careful not to consider such a vision a dummy. To find out exactly the purpose of a dream, you will have to remember all its details.
