How many things provide immunity to sleep?

[gadren]

How many things (races, classes, feats, etc.) provide immunity in to sleep in D&D and Pathfinder? Please list any you think of.

So far I've got (updated):

Elves & Half-Elves
Dragonwrought feat
Dragons, undead, plants, oozes, and constructs.
Wakeful mind graft

Wakeful Mind Graft (Faiths of Eberron, 158)

Are you talking about creatures that don't sleep at all, or that are immune to magical sleep effects? If it's the latter, you can add dragons to the creature types.

Immune to magical sleep effects.

Out of curiosity, are there any creatures that don't sleep at all that aren't immune to magic sleep? That'd be kind of silly.

Elan: they meditate, like elves, but have no sleep immunity.

Outsiders don't need to sleep either, but they aren't immune to it (as far as I know.) Native outsiders still have to sleep though.
