The Dreaming HoldSu
You have a dreamspace, and you did not build it — you woke up in it. It functions as the Dreamspace feat, except as follows, and you have it whether or not you meet that feat's prerequisites.
It is 20 ten-foot cubes per character level, and it persists whether you are in it or not. You may enter it as a move action from anywhere and leave it the same way; you do not need to sleep to do either. Leaving returns you to the space you last entered from, or the nearest open space, unless another ability gives you a different door. It counts as a dreamscape, a mindscape, and a plane for every effect that cares, with no spell point surcharge.
You may bring willing creatures in with you by touch, one per character level. They may leave whenever they choose. Nothing else enters unless you allow it, and no teleportation, planar travel, divination, or scrying reaches it uninvited.
Inside it, you gain a +4 profane bonus on attack rolls, saving throws, caster level checks, and your dream DC, and you may reshape its interior as a standard action rather than adjusting only its style. Time inside runs at whatever rate you set, to a maximum of 2 hours inside per 1 hour outside.
A creature other than you reduced to 0 or fewer hit points inside your hold is defeated: it is expelled, stable, to the space it entered from.
