Jag läste de magiska reglerna.

Some spells restrict you to willing targets only. Declaring yourself as a willing target is something that can be done at any time (even if you're flat-footed or it isn't your turn). Unconscious creatures are automatically considered willing, but a character who is conscious but immobile or helpless (such as one who is bound, cowering, grappling, paralyzed, pinned, or stunned) is not automatically willing.
Så längre ner är SR
Spell resistance is a special defensive ability. If your spell is being resisted by a creature with spell resistance, you must make a caster level check (1d20 + caster level) at least equal to the creature's spell resistance for the spell to affect that creature. The defender's spell resistance is like an Armor Class against magical attacks. Include any adjustments to your caster level to this caster level check.
The spell resistance entry and the descriptive text of a spell description tell you whether spell resistance protects creatures from the spell. In many cases, spell resistance applies only when a resistant creature is targeted by the spell, not when a resistant creature encounters a spell that is already in place.
The terms “object” and “harmless” mean the same thing for spell resistance as they do for saving throws. A creature with spell resistance must voluntarily lower the resistance (a standard action) in order to be affected by such spells without forcing the caster to make a caster level check.
Och till sist SR
A creature can voluntarily lower its spell resistance. Doing so is a standard action that does not provoke an attack of opportunity. Once a creature lowers its resistance, it remains down until the creature's next turn. At the beginning of the creature's next turn, the creature's spell resistance automatically returns unless the creature intentionally keeps it down (also a standard action that does not provoke an attack of opportunity).
Det framgår inte alls hur SR fungerar medan du sover, men från att läsa de tre olika delarna så tycker jag att SR alltid ska vara aktiv medan du lever, och du lever när du sover. Endast när du sänker aktivt är din SR nere.
Så, orsakar sömn din SR att sänka?
Titta på det så här: det anges inte någonstans som sömn gör sänker din SR. Du är hjälplös medan du sover, men det har ingen effekt på SR - det förhindrar faktiskt att du frivilligt sänker din SR. Och, som sagt här:
A creature with spell resistance must voluntarily lower the resistance (a standard action) in order to be affected by such spells without forcing the caster to make a caster level check.
Du kan inte sänka din SR på annat sätt om inget uttryckligen säger att du kan.
Så, ingen stavmotstånd sänks inte under sömn.
