Maddy's murder scene has a couple of very scary things in it. The first time Maddy comes into shot, with the spotlight over the doorway (Uncle Leland? What's that smell?) is somewhat horrifying to me. Then the sound effect of Leland punching her nosebone in half is really gruesome. I can only go by how I felt seeing these things for the first time all those years ago, but that scene was pretty much the worst for me.

The first ever shot of BOB, crouching down as seen by Sarah - that used to make me scared to go to bed at night.

Finally, the shot of BOB in Laura's bedroom, behind the dresser where she keeps her secret diary (in FWWM). That one never fails to give me chills.

So, like most people, the BOB moments are the worst for me. My girlfriend doesn't mind them so much - but she leaves the room whenever they check someone's fingernails for particles - LOL

And it comes as no surprise to me that Ivalinda isn't afraid of BOB! I think she'd like to marry BOB, if she could!

The night shots of the empty Great Northern hallway and RR parking lot before Maddy is killed are pretty eerie, too

They broke the mould, Ivalinda. They broke the mould......

I agree with the first post in here.

There many things in Twin Peaks which were shocking, scary and so on. But the one which was par excellance FRIGHTENING more than any other is indeed the first full vision of Laura's murder that we see - as we look through Ronnette's eyes at the end of Ep.8.

Of course the main thing we could use as counterexample is Maddy's murder. And sure - it is as a whole STRONGER. But not just because of plain SCARE that it arouses. There's more to it - first of all it's totally shocking to see that it is Leland, then - because it is something new that is happening again. Laura's murder is horrible to watch but after all we had known that she was dead anyway... in Ep.14 a truly new tragedy occurs :-(

But the most frightening in the basic sense of the word - is Ronnette's vision.

an episode toward the end of season 2. Coop has returned from a major police operation. (Possibly the stand off with Renault, i can't recall). He puts his jacket onto the coat hook in his room, turning smiling to himself, maybe deep in thought of pleasant memories(Annie?) he suddenly stops. Mouth turns into a frown. Cut to his bed. That mask...

Interesting you should mention it - actually I wouldn't call it frightening, it's too much of a stage-play effect to be terrifying, but I truly like this moment.
Especially what you call "deep in thought of pleasant memories". Before he enters his room he walks through the corridors of Great Northern in such a relaxed way, whistling a tune which makes a perfect match with the Badalamenti music in the background. I appreciate this moment a lot, also, it comes right after the rather tense finale of the Evelyn/Malcolm trouble, and creates a great counter to that scene where Malcolm pretends to be BOB ;-).
Let's not forget that Coop actually passes by a disguised Earle in the hotel elevator! So we know he has just been there. 

But Page Ripped Out, it's nice to see how you mix the events from different episodes :-)))
What you are referring to is Ep.22, so Annie was nowhere to be met in Twin Peaks at that time. While Renault was already dead... he he he :-)

I'm not sure, too, but does Cooper really come into his room all relaxed?... I know there is one moment when he comes into the room relaxed and then something unexpected happens, but also another scene where he notices something is wrong before he opens the door, so takes out a gun and comes in very alarmed. Wasn't the latter right before the Caroline mask?...
Somebody help me out please :-)

P.S. Perhaps some of the newer members don't know yet that this episode is for no good reason considered the worst episode of the series by many fans and related to (with contempt) as the "Diane Keaton episode". THis is of course absurd as the episode is one of the best that happened after Leland's death

The scene that disturbed me most was when Maddy was murdered. It was just grotesque.

Oh, and obviously the Bob crawling over the sofa scene was rather frightening.

What about every time, after we discovered the identity of Laura's killer, Leland's faked crying face suddenly turned into an evil grin. He was brilliant at pulling that off. 

I'll agree with most everyone that Maddy's death and the Black Lodge scenes in the last episode were the most frightening for me.

 The thing about Maddy's death was the atmosphere in the room. No music, no other people, just the click of the record player for what seemed to be an eternity. Whole thing just gave me goosebumps.

These scenes maybe disturbing to some, but not to me.  Most are beautiful. It is like Pasolini, or Bunuel the images change us or horrify. We are left with are imaginations. I could have long list of moments that were brutal with violence and incest. I still see it all as beauty, colour, texture, light and lack of, human nature and surrealism. Lynch is a painter.  

That scene is disturbing!

It actually is a little more cryptic than the FWWM murder scene.
