Headscratchers: Insidious

  • When Josh meets up with the red-faced demon, his physical body shakes violently, and all of the light bulbs shatter. Except for the light bulbs in the flashlights.
    • Just throwing something off the top of my head here, but maybe because the Houselights had been in the same area as Dalton for awhile, they're conditioned enough so that they're vulnerable the demon's powers. The flashlights however are new and used by people expecting the worst, so they're more sturdy.
    • Maybe the spirits are destroying the lights by overloading them. Notice that only the lamps that are turned on shatter.
    • Going by Dungeons & Dragons logic, held objects get a will save.
  • At the end of the second film, what good is hypnotizing Josh and Dalton to forget their astral projection abilities? In the first movie, Dalton had no problem using them without being aware of them. That's how his soul was captured in the first place.
    • I second that. It just doesn't make sense.
    • Correct me if I'm wrong, but I've got an impression that Josh had been hypnotized before when he was a child to prevent him from going too far into the astral plane the way Dalton did in the first movie. Seems like you can only be affected if you are aware of these powers on some level. The kid knew he could travel to some kind of a fantasy world, he just didn't realise that was dangerous.
  • If Chapter 3 is a prequel to the events of Chapter 1 & 2, how come the Lipstick faced demon appeared behind Elise at the end when he was supposed to be following Dalton the whole time? Even more so, how did he get there?
    • The confusion increases at the end of Chapter 2 when he was obviously the source of that clicking sound and behind that girl when Elise gasped "Oh my god!". So if they got rid of him at the end of Chapter 1, and he makes an indirect appearance at the end of Chapter 2, how come he isn't the main antagonist in Chapter 3? Will Chapter 4 be a sequel to Chapter 2?
