Alexandru Sift was a Romanian biologist from Cluj-Napoca who spent decades photographing unusual phenomena in and around the Hoia-Baciu Forest.

In July 1953, he reported seeing another gray V descend into a hawthorn bush. Sift said when he pushed a stick into it, the stick and his arm became invisible. He said the incident was the beginning of his systematic investigations.

In one photo, Sift photographed the “disappearance of an apparition.” According to Pătruț, a male humanoid was visible to the naked eye and appeared to disappear instantaneously.

Another photograph by Pătruț shows a male head at ground level near the forest edge.

According to Florin Gheorghiță, the photograph of the cat was accompanied by a letter from Sift in which he claimed that he had dematerialized the cat through the power of his will.
