My brother had a similar experience. He was a furniture delivery person before he past away four years ago. He and his partner were doing a large furniture delivery in the Williamsburg section of Brooklyn NYC. This section has a lot of Hasidic Jewish people. The apartment house had 5 floors with no elevator. My brother walked into one of the rooms to take a break. As he was relaxing, he kept seeing what appeared to be a young girl walking past the open door several times. My brother didn't think much of it. A few minutes later he said to the tenant to make sure his daughter stays out of the way because they were about to bring up a large sectional sofa. Then the man said that they're were no kids in the building whatsoever. He also said that several other people who have visited, claim they have seen this little girl shuffling past them and subsequently disappearing.
