Somebody who has cast Alarm is sleeping inside the area (they didn't choose the window or door option) of the spell, which is "[...] no larger than a 20-foot cube.", and the spell also states:
Until the spell ends, an alarm alerts you whenever a Tiny or larger creature touches or enters the warded area.
If I get a 10 ft pole and poke the sleeping caster gently, does the Alarm spell go off? I can see two parts to this, is the 10ft pole considered part of me as a creature? And have I entered if I've not 'set foot' inside the area? It's a little ambiguous if the 'touch' part is only intended for the door/window option.
Is it any different if I attack into it from range, with a spell or weapon?
