All I can say is whoever wrote this was channeling the mind of a 12 year old child. Try holding your breath for as long as she swims underwater (not once but 3 times in freezing water) or consider how she burns an entire pile of cash instead of using a couple bills as tinder. The fact she doesn't even wait for the lighter to dry off before throwing it away. The multitude of flashbacks start ok but soon become the entire movie. I'm really not sure where the disconnect is here, but it's just unwatchable. As at least one other review here talks about, the writers have never spent any time in the woods.
Spoilers ahead, if you care.
I at first thought that the entire thing was an allegory about purgatory, happening after she actually died in a fire early on (in the timeline she lives) which would have almost worked in a soap opera/telenovela way, but it's not. A quick Google search has quotes from the director saying there is no deeper meaning. Which makes all the weird dream sequences and flashbacks even more irrelevant.
