Out of This World (1987)

S3E5 Eviegeist

After Evie contracts the Antarean flu, her abilities spiral out of control. When Kyle sees her powers in action, he mistakenly concludes that the Garland house is haunted and hires a ghostbuster to exorcise the supposed spirit. However, once the ghostbuster departs, Evie and Donna come to a startling realization: there is, in fact, a genuine ghost residing in the house.
