This question applies to a number of situations, but most easily with the Tough Guy's basic progress card, Taunt. Taunt reads: "If any Entity inflicts you [STRESS], Stun that Entity (until the end of this Turn)." Stunned reads: "No [STRESS] effects this Turn" If an entity would target more than one dreamer with the same e.g. Basic Action, do the players have the ability to cause their Tough Guy to be targeted first and, if Taunt is installed, stun the entity, thus negating the stress that would have been caused to the other dreamers.
Do the effects on cards/entities that affect "each dreamer..." happen simultaneously, meaning there can be no other effects that interrupt that e.g. stress. I think this also applies in Dream II-02, because of various token interactions, but an answer to this question would help that one without spoilers. Thank you!
