Dreams are series of images you see in your sleep and are a form of communication from God to man throughout the Bible and today. Seeing a dream inside of a dream is significant and means that God is really trying to tell you something.
Positive: Having a dream within a dream is God trying to get something important across to you. You need to pay close attention to and analyze whatever God is showing you in the dream within the dream.
Negative: Having a bad dream within a dream is a warning from God. You may have recurring warning dreams where God is trying to show you something that will happen in the future so that you can prevent it.
