I have now been schooled....by our pediatrician.
HUGE difference folks, so this is my PSA.
The child does NOT wake up fully.
The child does NOT remember anything the next day.
The child WILL scream bloody murder.
The child WILL calm down and go back to (all the way) sleep fairly quickly.
The child DOES wake up fully.
The child DOES remember the bad dream VIVIDLY.
The child might or might not scream, but will definitely be afraid and tears are probable.
The child will take a LONG time to calm down and go back to sleep because the child is scared to have the bad dream again.
Let me tell you that NEITHER one of them are fun at all, but they're VERY different experiences.
