What would death from combining an MAOI and a drug like ecstasy look like in respect to symptoms?

When you take an MAOI along with a drug such as ecstasy, there is a very high possibility that it will kill you. MAOI stands for mono-amine-oxidase-inhibitor, or in other words, it is something that blocks the reuptake of neurotransmitters, causing the neurotransmitters to remain in synapses longer and in higher amounts. Ecstasy causes your brain to produce more serotonin. With this increase in serotonin and the effect of the MAOI, you could die. What would a person who experiences death this way feel like? What symptoms would they experience?

What does experiencing death by "natural causes" feel like? Since none of us have been there, I suspect you may have a difficult time finding an answer to that question.
