Pathfinder plane of dreams.

[Doomboy911]

So I'm reading that on the plane of dreams I can cast spells I normally can't by making a charisma check. Would I be able to use this to cast spells to travel to different planes or into others dreams?

The Dimension of Dreams is its own place with its own strange rules. I would allow you to cast spells to bring you to other dreams/planes, but they're still not real. They're just what your dreaming mind imagines those dreams or planes to be like.

Combined with Dream Travel, though, a friendly Lucid Dreamer could perhaps get you some spells out of schedule. Polymorph Any Object, Permanent spells, Wish for Inherent bonuses, various fix-it spells like Greater Restoration or even True Resurrection....

Edit:
And now that I've got a full desktop in front of me...

And the relevant bit:

A lucid body is not the only way to enter a dream, however, and considerable danger faces the explorer who enters the Dimension of Dreams in his physical body.

Regular methods of planar travel like plane shift do not offer transit to the dream world—only specialized means such as the dream travel spell do the trick. When a physical creature enters a dreamscape, he doesn’t have to make the check to determine his initial state, but also can’t attempt impossible feats (see below). Spells cast, magic items used, and other limited abilities expended are lost just as if the creature were adventuring on some other plane. Creatures in their material forms can use items generated within a dreamscape, but these items wink out of existence when the primary dreamer awakens, or when a creature in material form leaves the dreamscape.

Wounds and experiences are real, and remain after the creature leaves the dreamscape. A creature in its physical form that dies within a dream demiplane actually dies.(Emphasis added)

So while items wink out when you leave... if you were there physically, other things do not. If I go to a friendly lucid dreamer's dream, and get healed there... well, that's not on the list of things that go away when the dreamer wakes up. If I get both Enlarge Person and Permanency from a lucid dreamer... well, I'm going to be big for a while. And so on.

Thoughts?
