Does Dreams of R'lyeh works with minded undead?

[Beorne]

Do they sleep?

[Kristoffer O]

The mindful dead dream of golden days, and mourn that all their dreams have turned to ash and dust.
In despair they scream, until slowly, they loose their memories to the mind-shattering dreams of the void.

Ftaghn!


I'm not sure, but I think they are affected by the spell.

I tested Vengeance of the Dead once and it did affect neither undead nor demons as they don't sleep. I think, this case is similar
