Pentagram dream meaning is explained below using 3 different sources. Each interpretation is shown with its source.

Interpretation 1 — Dr. Mıchael Lennox

The pentagram is a widely misunderstood symbol; it has its roots in Christianity but is often used in the media in an inverted shape to refer to elements of the evil side of the occult. Its pure meaning connects to the five senses and the experience of the human body. In early Christianity it connects to the five wounds suffered by Christ. In the Tarot, the pentagram connects with money and prosperity. Any of these meanings might be expressed by a dream that features this geometrical image.
