This kind of dream may indicate that you are being tempted to fall back into old patterns and ways of thinking. Depending upon who the person is in the dream, and what this person represents to you, these dreams might also be an indication of your need to renew your former desires and godly passions for good things in life.
Seeing a person from your past does not usually mean that you will literally renew your old relationship with that individual. Look more for what that person represents in your life – for good or bad. A person who was bad in your life may represent God’s warning to you not to relapse into old habits and mind-sets that were not profitable. On the other hand, a person who was good in your life may represent God’s desire or intention to restore good times that you thought were gone.
