Things to look for

Time Code	Description
08:13	When Kim is lying on the grave looking up at the others, in one shot the word "Treacle" changes to "Further".
08:27	The shadow of one of the gravestones as they are leaving the cemetery is the Blair Witch stick figure (hereinafter referred to as Stickman). When the group have walked over the shadow, it returns to its correct shape
08:54	Stickman shape to the left of Tristen's head in the van.
09:57	Guy working on the fridge in the shop is referred to in credits as Rustin Parr. And his tools are arranged in the shape of a Stickman (next to his right elbow).
13:21	The word "ME" is visible to the left of Erica when she lies back in the woods.
15:05	When Erica lights Kim's cigarette in the foundation at night, the word "SEEK" is formed out of the fire for a couple of frames. You'll need good freeze-frame to see this.
15:35	Stephen exhales smoke and (again, only for a couple of frames), a screaming face is visible in the smoke.
22:27	When Tristen holds the baby under the water, a Stickman shadow can be seen drifting across the river from bottom-left of the screen towards the centre.
30:07	Spooky one this: when Jeff is being questioned by Sheriff Cravens, the reflection of the back of Cravens' head in the interview room mirror turns into a skull face.
30:38	As Jeff enters the house and rounds the corner to enter the corridor of cameras, the door to the left of him in the background appears to show an image of a ghost girl.
32:21	When Jeff is talking to Stephen and Tristen, there is a Stickman in the large window.
39:33	Another Stickman is in the window at the left when Erica is rooting through the fridge.
41:51	Once Erica and Stephen snap out of their worrying hallucination and appear at opposite ends of the table again, the word "NO" is in the window in the background.
45:10	Rustin Parr and his Stickman tools again, this time they're beside his head on his left. Interestingly, he also says "I'm finished now", which is quite similar to the "I'm finally finished" the real Rustin declared after killing the 7 children in 1941.
47:02	During one of Erica's invocations to the goddess of the underworld, Persephane, you can see the word "OR" in the carpet she is sitting on.
47:09	Not sure how much of this is just my imagination, but when we see Tristen looking out the window, and the camera zooms between her reflection and the owl outside, the bit in-between kind of looks like a child standing in front of an adult (Rustin Parr?).
47:45	The hole in the van window formed by the rednecks' brick is in the shape of an owl, spread out like the one that fell through the roof.
48:00	Another for all you with decent freeze-frame. When Kim crashes the van into the tree, there is a very brief shot of the woods, and on the left of that there's an upside-down pentagram (a symbol of evil and chaos when upside-down).
48:05	Stickman shadow on the side of the van when Kim gets back in it.
50:34	Not sure if this is a message or just a brand name or something, but there are words in the window behind Stephen and Tristen in their room. I'm pretty sure they're not there in any other scene in the room. First word kind of looks like "FLOOD" and I'm not sure about the 2nd. Help please!
50:47	As Stephen leaves the room, there is a flash of light on the door. Look closely and you'll see it's a boy's face.
56:12	The Stickman to the left of the fridge again.
59:33	Interesting one, this. At the shot of the house when Stephen is hanging from the bridge, the window appears to contain a huge Stickman, and the space between the window and the door towards the top shows a gigantic screaming face.
66:45	Not a hidden image per se, but what Tristen says in gibberish appears to be the best backwards pronunciation possible of "the children will again walk free". Some people have had trouble with this one. Write down that phrase backwards. Try pronouncing it. It sounds the same as what Tristen's saying.
70:02	This one's towards the end of the video when they play it backwards. When Tristen is staring into the camera, there is a flash at 06:23:58. You think nothing of it, and assume it's a camera glitch. Freeze-frame it and you'll see 2 images: the first is a screaming face, and the second is blurry but my best interpretation is it's Rustin Parr. Also note that the huge tree is also there, rather than the twig that the film has always shown. And the house walls appear to be back as well. Just like the house was back in its intact form in BWP. Very creepy.
75:57	Not very hidden, but in these shots of the Chinese man's coat, there are upside-down pentagrams all over it. Probably just a pattern, but you never know.
82:55	The final two words to the message: in the credits, as the Assistant Set Decorator's name approaches the top of the screen, pause it and you can vaguely make out the word "DEATH" on the left of the screen and "FIND" on the right.
