There is no future mood tense. There used to be, and a couple of words survive in fixed expressions, but for all practical purposes it is gone.
Also worth knowing: the past mood tense does not distinguish line from point. One form covers both.
Always start from the they form of the point in the past, then change the final o to an a.
hablaron → hablaran · comieron → comieran
From there work backwards for the other people, and the accent does not move.
Where quiero que needs the present mood tense, quería que needs the past one.
Quería que comieran con nosotros · Esperaba que me llamara · Necesitábamos que hablara con nosotros · Volví a llamarte para que organizáramos
English says I was hoping that he would call me. Spanish says I was hoping that he called me, with the past mood tense.
Besides otra vez, you can use volver a, literally to return to doing something. It is very common and has nothing to do with actually returning.
vuelve a cerrarse = it closes again
The a is there because volver is a verb of movement.
No quiero que vuelva a pasar · No quiero que la puerta vuelva a cerrarse · Volví a llamarte
A genuinely useful tactic while the past mood tense is still slow to build.
Using a plain "to" form sidesteps it. Finding these forms is time-consuming at first, and much quicker once you have practised.
Pasar, ocurrir and suceder all mean to happen, and pasar is the easiest.
Puerta is related to port: stress the o of port and it splits to give puerto, then change the o to an a for puerta.
No quiero que la puerta se me cierre otra vez
