Dream sequences in the Friday the 13th films.

The inconsistancies in the Friday the 13th series can all be explained if you view the endings of all the films as dream sequences.

Friday the 13th-
The girl at the end is attacked by a zombie Jason kid in the lake.
This turns out to be a nightmare, and is contradicted by Jason being alive and an adult in part 2.

Friday the 13th Part 2-
The girl at the end is attacked by an unmasked Jason with a machette in his shoulder.
This turns out to be a nightmare, and is contradicted by a scene showing Jason still lying there where he was shoulder chopped. Also, the unmasked long haired wildman Jason contradicts how he looks in 3 and 4, so this is obviously a nightmare version of Jason.

Friday the 13th Part 3-
The girl at the end sees Jason up and around after getting an axe in the head, and then is attacked by a rotten zombie Pamela Voorhees in a parallel to the ending of part 1.
This turns out to be a nightmare, and is contradicted by Jason still being "dead", in the opening of part 4, and that Pamela Voorhees was decapitated, and long since buried.
Also, Jason's appearance is contradicted by how he looks in part 4, so part 4 Jason must be how he REALLY looks (at least when alive).

Friday the 13th: The final chaptor-
Tommy Jarvis looks traumatized, and kind of loony after his ordeal with killing Jason.
This, and Tommy's resemblance to young Jason, seem to imply that the filmakers were going to make Tommy the next Jason.
Nothing much really happens here, but since Tommy DIDN'T become the new Jason, this is contradicted, and could therefore be a dream.

Friday the 13th Part V: The new Begining-
At the end, Tommy seems to see the ghost of Jason, and then puts on the hocky mask, and attacks a fellow surviver. The way this is filmed is consistant with the dream scenes in the first trilogy, and is contradicted by Tommy being a good guy in part 6.
Also, reference is made in the opening of part 6 to Tommy wanting to cremate Jason to end the nightmares and hallucinations.
Plus, the opening of part 5 shows Tommy having troubling nightmares of Jason, setting up right there that he has nightmares and visions.

Friday the 13th Part VI: Jason Lives-
Nothing much happens here except for Jason being chained to the bottom of the lake, and then just before the credits, he opens his eye.
Take this as you will.

Friday the 13th Part VII: The New Blood-
The telekinetic girl seemingly ressurects the spirit of her dead father who dives out of the lake, and chains Jason. This is consistant with the boy Jason/zombie Pamela Voorhees ghost visions.
Also, she passes out, and awakens not sure if it was a dream.
Nonetheless, Jason IS chained. I think her father was a hallucination, and her telekinesis chained Jason.

Friday the 13th Part VIII: Jason Takes Manhattan-
The ever controversial "Jason melts, and turns back into a boy", scene.
This fits the pattern of ghost visions in the water, and is contradicted by Jason being back in part 9.
My theory that "Jason goes to Hell", is 10 years later, so Jason ages back, would also make up the difference.
But, I'm slightly uncomfortable with it, as it requires a lot of supposition without direct evidence in the film.
Having the meltdown be yet another boy Jason/Pamela Voorhees/TK girl's dad drowning vision is consistant with that scene, the series, and the contradiction of 8 and 9.
Also, having the toxic waste mutate rotten zombie Jason into lumpy tumor ridden Toxic Avenger Jason in part 9 makes sense. It explains the coronor determining his age to be in his 40's (how old he'd really be) and the nerdy morticion calling him "maggot head", implying he's still the same zombie.

Jason goes to Hell-
Jason is pulled into hell by rockmen demons, and then his mask is pulled down in by Freddy's hand.
Although, this sets up "Freddy vs. Jason", and connects to "Freddy's Dead", this scene is reminiscant of the scenes of zombie boy Jason pulling the girl down, Pamela voorhees pulling the girl down, and TK girl's dad pulling Jason down.
Also, it contradicts the begining of Jason X.

Jason X-
Corona Coming Attractions has a scoop report on the script of the upcoming 10th Friday film.
According to the scoop, Jason really didn't go all the way to Hell, and the military retrieves him to ty to make him a weapon.
This goes awry of course, and Jason goes on a rampage.
Jason then gets frozen, and reanimated 400 years later in the post apocolyptic future by space archeology students. Of course, Jason then goes on a rampage.
There are also rumors of Jason being rebuilt into a cyborg Jason!
The ending of course, is unknown, but I'm betting on it being open to being a dream to make way for an 11th film.
After all, the plan has always been to make it to part 13 someday!
