Dark Vail During A Funeral

My friend's uncle passed away few weeks ago. I went back to Brazil for his funeral since he was one of the helpers who introduced me to my grandmother's tribe. No, not a person from the tribe but something like a tour guide?

If it is not for him, I would never have met the same tribe my grandmother was in. For people who did not understand that my grandmother is a native tribe in Brazil called, Tapirapé. They are very mysterious and not too open minded, which means they rarely communicate with outsiders.

Right, so my friend's uncle was like a middle person, who gave me a chance to get contact with those people. (I do not think I became a friend to the tribe but some of the elders still remembered my grandmother).

During the funeral of my friend's uncle, in the air of sadness, I looked in the casket to say my final goodbye.

I could not look in to his face directly because I was afraid I will burst out crying. As I looked up and reached his face I thought I see a black vail on his face. I wondered if anyone would hide the dead man's face with a black vail... Normally not, right?

I looking again from the corner of my eye but saw no vail. I whispered to my sister "Viste o véu no seu rosto?" (Did I you see the vail on his face?)

My sister did a oh no not again expression and shushed me pointing her index finger to her lips. (yes, she had became very skeptical against paranormal stuff... I wonder if something happened)

I heard stories and experiences like that usually at active spots with tragic stories... Did my friend's family uncle want to hide his face to prevent me from bursting tears all over?
