A procession in the alley behind Double Door. View Full Caption DNAinfo/Alisa Hauser

WICKER PARK — Around 11 p.m. Saturday, a small group of people covering their heads with what looked like a long white sheet or tarp snaked through an alley behind Wicker Park's Double Door.

They shouted and chanted indecipherable words as they marched, mostly in unison.

A leader at the front of the line was walking backward and appeared to be guiding the group as they walked behind the 1500 block of North Milwaukee Avenue.

For now, it's a mystery to us.

Do you know what this procession was all about? Were you part of it?
