I once had a dream about Barney::
I came home from school one day and there was Barney, talking to my parents. I asked them what was going on.
"Oh, Barney is going to stay with us for a little while, and he's going to sleep in your room."
'Awesome.' I thought, because Barney scared me.
I wake up in my bed, sweating. And there's Barney, with a red light on him, hovering above my bed. And he starts singing.
"I hate you, you have me, we make such great enemies." And holds up a knife, as if to stab me.
That's when I woke up.
