Favorite examples of dream control backfiring?

So, what is your favourite example of your dream control backfiring?

One of mine was attempting to conjure up money in order to pay for my dessert, but instead they came out as chocolate coins.

Another was when I attempted to fly (I, myself, am usually quite proficient at doing so) but ended up flying at a ridiculously slow walking speed.

I "made" my dream characters sing "Let It Be".

There was a huge crowd, but there were a guy and a woman on a sorta stage thing. Halfway through the song, the guy stopped, started crying and saying how much he loved the woman and they started making out...
