Well... in my whole life I've only ever had this kind of weird thing happen during one short period when I was 13 years old in Sec 1.
And *that* was really quite scary. Because for 3 nights in a row SJ and I had exactly the same dreams, but in a weird way; you know how dreams sometimes have a "storyline", but when you wake up, some parts are blur? I was clear where hers was blur and she was clear where mine was blur and everything matched into a coherent whole. It was definitely the same dream because the blur parts were WITHIN scenes and they matched in every detail.
Around the same period of time, 4 of us were having weird similar dreams also. In which the story was different, but the characters were exactly the same, and the basic plot was exactly the same. And everyone dies in exactly the same order.
Weirdest part of it all? We were all waking up at the same time in the mornings.
Talk about scary.
Because it was at that time that we were experiencing a lot of spiritual attacks and strange manifestations. No kidding.
