Pondinium

From Tardis Wiki, the free Doctor Who reference
You may be looking for the comic story Pondnium!.

Pondinium was a beautiful planet with the added attraction of being covered in small ponds and puddles of psychic resonance particles that cast a reflection of possible versions of a person's own future by tapping into thoughts buried really deep down. The pools were created as traps by a stranded Aquarpey. (COMIC: Pondnium!)
