I've been brainstorming uses of these spells lately, and then saw a creative one on GiTP. Has anyone else got ideas?
1. Hide permanently asleep low level enemies (via Binding) as teleportation (or at high levels via Dream Voyage, plane shift) beacons. Bestow Curse for low saves for best results.
2. Reach otherwise hard to reach locations like the Dimension of Dreams, a wizard's demiplane, or a deep layer in an outer plane. May require a combo with Demand to force an outsider to go to sleep and give you a target if you don't know a convenient creature who has to sleep that lives in the relevant location.
3. Use these spells as safe places to sleep or otherwise recover, similar to Rope Trick or Mage's Magnificent Mansion. There's nothing forcing you to enter the dreamer's dream (or exit to the real physical location) once you arrive, so just hang out and sleep on the boat until you're ready to return to your original location.
4. Enter a sleeping ally's dreamscape to take advantage of the impossible feat rules to get beneficial spells cast on you.
As a standard action, a number of times during the dream equal to the creature’s Charisma bonus (minimum 1) the dreamer can attempt one impossible action, such as casting a spell, gaining an effect of a spell as if it were cast, or conjuring a magic item. This requires a successful Charisma check (DC 10 + the level of the spell being cast or spell effect replicated or half of the caster level of the item conjured; nonmagical items are caster level 0). Other fantastic feats are also possible with GM approval and a Charisma check with a DC determined by the GM. If the check fails, the dreamer cannot perform the feat. Creatures that enter the dream with their physical bodies do not need to make the initial check and do not gain the ability to create items and spell effects or perform other fantastic feats, but must otherwise deal with the strange realities of the dreamscape.
A personal physically present in a dream via one of the spells under discussion is subject to damage or death in any dreamscapes he visits, and should (ask your GM) also retain any positive effects he suffers...including those from the spells that dreamers there in a lucid body can provide. So if you visit a friend's dream in the flesh, he should be able to dream you a Remove Curse, Heal, or Polymorph Any Object whose effects stick with you when you return to the material world. (He should even be able to use a Wish to grant you those stacking +1s to attributes, but don't push it.)
For 3. there is a reason not to hang around outside the dreamscape. Each hour waiting on the dimension of dreams requires a will save to avoid rolling on a table of bad things.

True, but not for Dream Voyage. A dream discipline Psychic could burn off an 8th level slot at the end of the day on that. The
I'm not sure - the dream vessel protects against fear and emotion effects, but some of the stuff on that table is neither. It may be speed which helps protect against those effects in normal use.
That's a lot of people you can move with the dream voyage spell. 160 per casting for a 16th level dream psychic. Possibly enough to start colonising the planes.

Dream Travel notes: "These effects are considered emotion effects, in addition to any other descriptors that apply." So you're fine.

Looking at both spells again, I'd thought that Dream Voyage, at least, allowed you to hang out in the ship adjacent to but not in the target dream. But I don't think that's right. Instead it looks like you automatically enter the dream, but can (1) remain in the ship inside the dream, (2) disembark the ship inside the dream, or (3) disembark the ship and try to enter the real world.
So trying to rest in someone else's dream is pretty risky unless you (1) know the dreamer won't try to attack you or can prevent it (charm/dominate?), and (2) can prevent the dreamer from waking and stranding you (if using Dream Travel) prior to you finishing your own rest. If you're trying to hide out rather than rest, or want everyone but the spellcaster to rest, it looks like with Dream Voyage you can just ping pong the ship back and forth between the target dreamscape and the point of origin until the duration expires or the target wakes up.
