Short backstory: The party was freed from imprisonment by a cult member who then ran off to make a distraction, to facilitate the party's escape. It's been several in-game months now and the party has managed to re-establish contact via "Sending", only to discover that he is going/has gone insane and potentially is having his mind messed with. They've just leveled up, and in a bid to get more information on the guy, on what's happening to him, and on the cult which they're now fighting, the party Wizard had a fun idea: cast the newly-discovered spell "Dream" to allow for longer communication (including modification of the guy's dream world). The plan is to send in the party Fighter.
However, the target in question is known to have been driven at least partly mad by hostile influences on his mind, and the party suspects (and rightfully so) that entry into his dream and mind might mean they need to struggle against those same hostile influences or at least that his madness would manifest in ways that pose danger. There is also a danger the party hasn't foreseen: entities will attack the party (including Fighter's tranced body) in an effort to stop the dream intrusion.
The question involves the party Paladin: if your body is within the Aura of Protection, do you benefit from the spell? If the party Paladin is holding the party Fighter as the Fighter sleeps, then does the Fighter gain the save-related benefits of the Aura of Protection even though their consciousness is very far away in the mind of the other man (and thus out of range)? It specifies that the Paladin must be conscious to grant the benefit, but the target need not be conscious to accept the benefit (as is the case when the same Aura provides benefits to Death Saving Throws for a downed party member).
TL;DR - If a Wizard casts Dream, sending in a Fighter as the messenger into the mind of a madman, does the Fighter benefit from a physically nearby Paladin's Aura of Protection bonus to saves as long as their body is in range? Or must the body of the spell's target (and thus the messenger's consciousness/essence) also be within range?
