Bilocation

Bilocation, or sometimes multilocation, is an alleged psychic or miraculous ability wherein an individual or object is located (or appears to be located) in two distinct places at the same time.

Spectral evidence
Spectral evidence was testimony that the accused witch's spirit (i.e. spectre) appeared to the witness in a dream or vision (for example, a black cat or wolf). The dream or vision was admitted as evidence. Thus, witnesses (who were often the accusers) would testify that "Goody Proctor bit, pinched, and almost choked me," and it would be taken as evidence that the accused were responsible for the biting, pinching and choking even though they were elsewhere at the time.
