Aubrey Appel tells TMZ ... she and her husband, Dave, turned the lights off on their display Sunday, and took down the levitating Max figure after a neighbor called the police. However, no official complaint was filed.

For those unaware, the insane display in Plainfield, Illinois is highlighted by Max Mayfield from the Netflix series seemingly floating in midair ... a reference to the latest season of the show.

Their setup's gone viral during this Halloween season, apparently too viral for some! Aubrey says the neighbor in question called cops after someone pulled into their driveway and walked on their lawn to check out the Appels' home.

Aubrey and Dave tell us they had reached out to all their neighbors before putting up the 'ST' homage and had the neighborhoods' full support. After the one neighbor's complaint, they were planning on taking everything down this week -- but had a change of heart due to the overwhelming amount of support they were getting.

Dave met with City Manager James Capparelli Wednesday and was told they were doing nothing wrong and had nothing but support for their home haunt.

Moving forward, they'll only be in full operation on weekend nights ... people can still take a look during the day if they want, but the lights will be off. Max will be "levitating" as long as winds are below 10 MPH, otherwise she'll be at her stepbrother Billy's gravesite.
