You've just walked on stage, staring out into a big empty space of the Avalon Theater, a Hollywood staple since 1927. All of the sudden, applause erupts for you — except there's no one there, and it's definitely not a sound guy messing with you. It's more likely you just got to enjoy someone (who is the question) relishing their television debut, over and over again.

It's called a residual haunting, something you will hear more about, and maybe even encounter, on this two-hour Hollywood Boulevard ghost walking tour. Expect outlandish stories (this is TinselTown, after all) based on everyday people's ghost encounters: haunted pool parties at the Roosevelt Hotel, an impatient ghost of a Warner brother trying to get to his office, and plenty more on a 1.5-mile stretch of this famed thoroughfare that still hosts some of Hollywood's biggest events.

Expect to learn more about paranormal happenings and ghost sightings at the Chinese Theater, the original downtown LA Pig N Whistle, Ripley's Believe it or Not, and the Knickerbocker Hotel, among others, on the ten stops.
