History YMMV / GhostAdventures

** The episode where Zak seemingly gets possessed at Preston Castle. He goes to investigate where he thinks the murderer-ghost is, then suddenly freezes and starts babbling about 'we shouldn't go down there,' and 'I don't feel so good,' while the cameramen look at each other in confusion. Then he suddenly wanders off in the opposite direction and the next thing you know, his buddies have found him sitting in the middle of some random room with his ''eyes glowing.'' Granted, the ghost in question seemed to be that of the victim and trying to protect Zak and the crew, but the image of him sitting serenely with eyes glowing like something out of a horror movie, seemingly focused on something nobody else can see, while he smiles this almost demonic smile and tells his buddies that he's perfectly fine...it gives me chills.

** The Lizzie Borden House episode, especially since they all but say that the apparent reason Lizzie killed her dad was that he ''sexually abused her'', and even though they beep a word it's pretty clear from context what tehy're talkinga bout. Even outside of the context of the historical murders that's pretty disturbing.

** Zak's grandmother died while they were investigating the Winchester Mystery House. Made even worse in the ending with it highlighting a photo of Zak that he gave to his grandmother (Who never missed an episode of his grandson's show, mind you.)

** Zak's grandmother died while they were investigating the Winchester Mystery House.

** It kinda gives the word "[[IfYouKnowWhatIMean ribbed]]" a whole new meaning.

** The death of Zak's grandmother during the investigation of the Winchester Mystery House.

** At Gettysburg, they got an EVP of a young woman saying 'I'm pregnant.' The team believes it to be the spirit of Jennie Wade, the only civilian casualty of the battle. It adds another layer of tragedy to an already tragic event.

* HeartwarmingMoments: Zak interviews a young girl named Bailey at the Stanley Hotel who has seen and interacted with the spirits numerous times. Bailey (visibly nervous doing the inverview, understandably) says that none of her friends know of her abilites/actions because she doesn't want them to think she's weird. Zak, in a departure of his [[LargeHam hammish]], [[NoIndoorVoice loud]] behavior, tells her [[RousingSpeech to not think about that kind of stuff,]] [[CrowningMomentOfHeartwarming and that the more she does it, the more she can change people's perceptions of the job]].

** If that one was bad, the [[{{Understatement}} incident]] on Poveglia Island was a million times worse - at Preston, it was just a spirit possession. On Poveglia, it was a ''demonic'' possession--out of nowhere, Zak started screaming and cursing at the other investigators (who are his ''friends''), hurling himself at the walls, and the look on his face... Not only did they leave out most of the footage because ''they'' were so uncomfortable watching it, they stopped an investigation for the first time to perform a cleansing ritual. Compared to that, the later catches of [=EVPs=] in English, despite Poveglia being closed to tourists for centuries, so the odds of someone dying who speaks English on the island are pretty unlikely, is relatively normal for the show's fare.

** At the Villisca Axe Murder House, along with some very disturbing EVPs, the team caught footage of a door - a ''wide open door'' - slamming shut on its own, immediately after some footsteps sounded.

* {{Narm}}: Can occasionally be run into, even with the genuine HighOctaneNightmareFuel.
--> Zak: '''"''THEY'RE IN HERE, BRO! THEY'RE IN HERE AND THEY'RE SCREAMING!!''"'''
** The machine that allows the investigators to speak to spirits in realtime. Apparently the machine makes spirits talk like parrots.

** There was the investigation in La Palazza where they had a woman who looked like the former resident of the house (who the ghosts/demons seemed to like watching shower while making lude comments) wrap a towel around her to appear naked to lure out these comments for recording. What they got instead was a demonic sounding voice screaming "'''KILL HER!'''"
