Just my option, but I have a bit of a different take than what I have been reading...
I did not see anything in the series that implied that Sarah is Judy/Mother. This theory seems to be taking on its own life in articles and forums but I am still not buying it.
Consider that all we ever saw Sarah do was act depressed in her house and act in self defense against a trucker who was sexually aggressive towards her. Judy is described as an incredibly strong evil force. What did Sarah ever do that was evil?
The "Mother" is another thing to take another look at. For one, there is no mention at all of a mother within anything we saw or heard on screen. The entity that spat out the eggs and BOB sphere resembled "The Experiment" and "Experiment Model" but the word "mother" was created in reviews and forums by fans, right? Am I missing something within the context of the actual show that described it as a Mother?
My point is that fans have conflated The Experiment with Judy and with the word "mother" because it seemed to give birth to BOB and other evil. With the word mother attached, the obvious parallel was Laura's mother, Sarah. But I don't see anything at all within the show that draws that line.
There was obviously something going on with Sarah but her actions are much more in line with depression, loss, and alcoholism to cover to all than with anything even close to behind inhabited by the ultimate evil force.
I'm also not on board with Sarah being Mother but there is at least one thing that would support this theory. When Cooper altered by past by stopping Laura's meeting with Leo and company, Sarah seemed to sense something was wrong, started moaning, and began stabbing Laura's picture. As if she was trying to make sure Laura still died.
If you look closely, you'll notice that Sarah is able to easily break the glass in front of the picture, but the picture itself remains intact. She is not able to tear or puncture it. Its as if the universe doesn't let her actually kill Laura, so instead Laura is put into a different reality.
I am a bit more comvinced that Sarah is frogmoth girl. Somthin' got IN her.
Mother is from Purple sea scene, rosette American girl ..
She took her face off and a toothed black faced thing came out and ripped a guy's throat open in almost the exact same manner the thing in the glass box killed the couple in NY. A scene which is immediately preceded by Sarah watching animals devour a cow alive on TV to drive the point home with a hammer. These aren't the actions of a human being, no matter how disturbed. The fact that this thing, The experiment, is mother to BOB, has nothing to do with Sarah being a mother too. That is coincidental. She didn't possess Sarah because she's a Mom. Rather at some point Sarah gave up hope and became vulnerable to her.

Yeah, but and then what? Sat around and drank? I just don't see the actions of a crazy evil spirit.

That's the second part of my theory... it's kind of long, detailed here: http://welcometotwinpeaks.com/discuss/twin-peaks-part-17-part-18/the-gold-orb-and-the-frogbug-laura-not-all-good-sarah-not-the-motherexperiment/

An important part of this scene is that, unlike the other scenes which Laura's body disappears, Jack fishes, etc, which are clearly the day Laura should have died,the scene of Sarah smashing at Laura's picture is present day. The large screen, flat TV she was watching is present. The fact that the glass breaking rewinds and goes forward a number of times suggests time is being messed with along with Laura.

You don't think ripping your face off and killing someone is the actions of a crazy, evil spirit? Okay. As far as what Sarah/Experiment is doing it's clear she's waiting for something as Sarah. Since Evil Cooper is originally supposed to go Sarah's house, where he expects to find Judy. before he is rerouted to the Sheriff station is a pretty clear hint she is probably waiting for her son BOB. Meaning Sarah is possessed by
BOB's Mom,/Experiment/Judy/Jowday.
Also, given the Palmer House is owned by a Tremond in the Carrie Page universe which was sold to her by a lady named Chalfont it becoming likely that--
21st century Sarah=Judy=Jowday=BOB's MOM=The Experiment=Mrs. Chalfont/Tremond
Some things make me think Sarah is Judy.
- Just how Laura shows good when she takes her face off, Sarah shows bad, and so this pins them as the opposite of one another. Dale's mission was in-part, to find a way to deal with Judy, and this is why i think he takes Laura to Sarah's, hence the two birds with one stone thing.
- Sarah otherwise serves no purpose whatsoever in the story. She's Judy. Just look at all we're presented with..

I would add to that that her stabbing Laura's picture and Laura disappearing from the woods in 1989 happen concurrently, and we hear "the sound" the Fireman told Cooper to listen to at the beginning of Ep. 1, after which he said, "It's in our house now."
Also, as far as Sarah/Judy not acting evil most of the time, people seem to forget that those who are only possessed, not tulpas or doppelgangers, are not under their possessors' control 100% of the time. Bob came and went when he was in Leland and Leland had no memory (until the end) of what happened when Bob was at the wheel.
'Mother' is only ever referred to in the purple room, and all we've ever seen or heard from it is banging on a door.
I don't believe THAT mother is the same thing as the experiment. It could be, but there's no actual hard evidence that it is.
I'm not sure of any of this, but if Sarah is inhabited by Judy, she may not be fully expressing that entity. Sarah could be fighting it by retaining some of her own personality. She could be keeping it at bay by consuming massive quantities of alcohol. She could also be cooperating with it in a symbiotic relationship. If she is a vessel for Judy, the evil may not have been fully unleashed as evidenced by the presence of white when she removes her face. Only the spiritual finger on the hand was black.
She has also been holding it back with massive quantities of drugs as you can see at least ten bottles of pills around her when the boxing match was on constant loop ( another battle that goes on forever by the way ). Also one armed Shoe salesman used to keep Mike in check with halperydol in season 1. Plus Bob and Mike were only able to inhabit and take over the actions of the host and whatever has gotten a hold on Sarah Palmer has a bit more juice running through it.... So judy is a greater possibility
I think she is definitely possessed by something. That much is obvious. But she only ever acts tortured and one time and one time only, she reluctantly acts violent in self defense. This just doesn't fit the description of ultimate evil force that Judy was described as.
