My rationale for the sleeping curse not having the Burning Red Room (before the show contradicts me):

The Sleeping Curse is made of a variety of components and like all curses, can be modified. So, let's start with the basic Sleep Spell.

A) Sleep Spell "Your body will be your tomb.": It knocks you out and put you in a temporary stasis. (You can't just shake them awake.) Proof's in 4x13, etc. Thus a stronger sleep spell likely could put you in an extended death-like stasis. This is the basic sleeping curse aka super strong sleeping spell.

This is where we get Mal's (Regina's?) version or additions to the sleeping curse.

B) "In there with Dreams formed of your own Regrets": This is spell that traps you inside your nightmares basically. This could naturally be apart of the basic sleeping curse, but not enough is known. I doubt though that Mal would be drugging herself with nightmare fuel, XD

C) Burning Red Room aka the failsafe. This was presented as just side-effects of the spell, but it could be something Maleficent added after it failed the first time. XD

We see a number of sleeping curses. I think most sleeping curses are just A+B. I doubt Regina was planning to add C to hers in season 3 and the B might just be a natural occurence of the curse. Likewise those not of Mal's are just A+B. This will be Zelena's as well. (The one with David could just be A+C).

Actually forget that! Mal just got the sand from Morpheus added that to some poppies and took some water from a river in the Underworld. Makes as much sense and they could just make Morpheus Lily's dad.
