Is this finally proof that we are not alone?

Eva Gray collapsed backstage after signing 'Goodbye Little Girl, Goodby' to crowds at the Biddeford City Theatre in Maine, USA in 1904.

Her spirit reportedly walks the building where she died aged 33 following her third encore for demanding audiences on Halloween.

Ghost hunters have now captured the first ever image of an apparition inside the building - built in the 1800s - which they believe is the ghost of Eva Gray.

Infared images taken at the theatre last month show a ghostly white figure in an evening dress standing on the stairs appearing to walk out of the building.

Another picture shows a creepy apparition looking out over the stage from the upper tier.
