This next post is not exactly considered Vodou and yet it is, so please excuse if i share my own personal experiences and idea's about "Gravediggers" and "Shadow" people's comparison. Only in the last year i have really put my efforts to learning more about Vodou and sharing what was pre taught to me and what i find on the internet or in books to have both valid and liable sources of practical usage and theory.
The Barons and Maman Brigitte are the main rulers of the Guede and they rule over every aspect of death, in some cases i have read where they are referred to as " Gravediggers " and/or the rulers of the " Gravediggers ". In my practice i have found this could be the case but i truly believe the " Gravediggers " are actually servants of the Guede and they are just as absurd, loud, and enjoy a good laugh as much as their leaders. These beings are the roamers in death and servants of the Baron's and Mama Brigette and travel in large groups. Weather these beings are souls of humans, or something higher on the chain i have no idea, i just know they serve the Guede.
"Shadow people" came to me a decade ago during a very intense astral projection experiment that was beyond more successful then i can put into words. During my astral travel i noticed two things right off the rip, the huge wheel's that were glowing with a silver luminesce (at the time i perceived them as spider webs and learned later i may have been seeing peoples life lines) and the shadow figures all over the place. They came in all shapes and sizes and some even noticed i could see them and that is when things got interesting. I studied them for what seemed like ages, never moving away from my body. I could tell i made them uncomfortable, or maybe they were picking up on my excitement and fear, as i was experiencing both hard to say. Either way i studied them for a time, and learned they couldn't actually hurt me, but they could intensify my emotions if one got to close. After observing what i could about these mysterious "shadow people" i left my state and returned with more information then before.
When i began working with my black mirror the first time ever successfully getting the thing to comply my first images were hundreds of humanoid like beings who walked from right to left. Every so often one would slow but never stop and look into the mirror at me. They were seriously uninterested in what i was doing, and they honestly just looked bored, but i noticed they had moments of sporadic change where they would move the arms up and down, or just distribute charges of random energy, then nothing but walking. It was almost the same radical behavior i seen before in my astral travels.
With that being said, i believe the "Gravediggers" and "Shadow People" i seen are one in the same, its not uncommon for others to have seen this strange phenomenon. It does give me hope that i am the right track in understanding spirit's and how they interact with us. In conclusion both events led me to pursue other types of spiritual contact. Of course as always i would be interested in other stories on the subject, until next time.
