Is there a spell that lets you Summon Items/Constructs/or Animal Companions?

[Sims]

I would picture myself as the type that didn't carry around a huge sack full of stealable stuff. That and, Animal Companions/Construct Slaves are awesome, but I wouldn't want them out at all times.

I could have sworn I read about a spell that let you put stuff in another Dimension, so do you guys remember what it was called?

EDIT: Hmmmmm...., probably couldn't store a Dire Bear Animal Companion there anyway....
