The weirdest one was probably the one where my aunt visited me and gave me a box of old toys. It had some broken non MLP toys like a Woody doll and a few Transformers and lots of ponies, some of them were in terrible condition so I decided to EAT all the non-MLP stuff and the baity ponies...
I ended up eating most of the toys before I woke up.
What's scary is that I, too, had a dream like this!
I got a bunch of dirty, nasty, baity ponies (I had this dream when I was new to collecting), and I was convinced that, somehow, the process of digestion would help to clean them. Then I realized that that didn't make sense, but by the time I figured it out, it was too late: I had eaten all of them, and was sitting, stunned and horrified, with the remains of a half-eaten Fizzy in my hand, a piece of her still in my mouth....
It was particularly scary because I remember the taste so vividly (like crayons or something)... and it was a horrible taste that I associate now with loss and foolishness..... Still gives me the creeps.
Interesting to know that I'm not the only one with dreams like this!
