Meltdown

A tantrum is a controlled rage where the person is intentionally trying to get their way by getting attention. It usually stops if the person gets their way or after a length of time without intervention and they can get embarrassed by others seeing their tantrum.

Whereas a meltdown is triggered by a sensory overload which is totally out of the persons control. They can be sometimes prevented if you are aware of their triggers Sounds and noises, light, crowded spaces, even smells can trigger a meltdown. They won’t usually resolve on their own, and ear defenders, quiet places with little or no stimulation and weighted blankets are needed to help a person having a meltdown. 

yes they can vary in severity and can manifest in different ways.. Without knowing the events leading up to the laying on the floor it is hard to say whether it is meltdown based or not. but hopefully with the above info you may have an idea which it is.
