[SPLIT LIP]

The first one sounds like a classic case of sleep paralysis exasserbated by the feeling of unease before bed. These kinds of waking dreams are not unheard of, and I bet if you had tried to move or get up you would have found you couldn't, like you were being held down.

The second also makes me think it could've been some kind of dream-like hallucination, given that you two were driving at night, your friend seemed to be acting strange. (knowing something that you don't, advising you, generally being an authority during the event is symptomatic of a dream)

The little girl, honestly may be yet another dream. If you're in this freezer, it's entirely possible you nodded off. Especially if you're unused to the cold like you said, and were performing a rather mundane task. You should be thanking this "girl" because the nightmare probably woke you, and who knows if someone would've found you.
