When the subjunctive fires: the map
The subjunctive appears in subordinate clauses after triggers of will, emotion, doubt, and unreality — typically with que and a change of subject: quiero que vengas.

Erklärung
The big families: wishes and requests (quiero que, pido que), emotion (me alegra que), doubt and denial (no creo que), impersonal judgments (es importante que), purpose (para que), pending time (cuando + future), unknown antecedents (busco alguien que...), and ojalá/quizás.
Same subject usually collapses to the infinitive: quiero ir (not *quiero que yo vaya). Certainty keeps the indicative: creo que viene, es verdad que llegó. Each family has its own stub.
