using the taser rounds to silently take down guards we come across with one shot.

again, real life silenced or movie silenced makes a big difference.
if it is more akin to real life, the silencer will do almost nothing, your silent takedowns will be heard through half the complex.

Both kinda? Leaning more towards "movie silencer" though, given our premise. "Dream Silencer" might be more accurate though.

Those taser rounds are actually subsonic, so the loudest thing will be the action cycling, not the crack you would get from supersonic ammunition that has been suppressed. The action cycling isn't THAT loud (speaking from experience) on a gun that has been tuned for subsonic ammo. If you happen to have a semi-auto shotgun handy, lock back the bolt and then hit the bolt release. It's noticeably softer than that, since the springs are weaker to account for the lower recoil.

Aside from that, everything will work how Daydream would imagine it to since she's creating them. Considering she's a Canadian teenager and therefore has probably not been exposed to guns in real life or ever did any research of note into them, and has been repeatedly exposed to movies and dream guns (neither of which are loud enough to damage her hearing), I think she'll expect it to be totally silent so therefore it will be.
