Eroto-comatose lucidity is a made-up word that combines three different concepts: eros, coma, and lucidity. Let me explain each of them to you in a way you will understand.
Eros is a word that means love or desire. It's like having a really strong feeling for someone or something that you want to be close to.
Coma is a state of deep unconsciousness, like a really long sleep where you can't wake up no matter what. You wouldn't even know that time is passing.
Lucidity means clarity of thought. It's like being wide awake and alert, like when you've had a good night's sleep and feel rested and refreshed.
So, when people talk about eroto-comatose lucidity, they are imagining a situation where someone has really strong feelings of love or desire (eros) and then falls into a deep sleep (coma). But instead of just sleeping and not being aware of what's happening around them, they have some kind of clarity of thought (lucidity).
This might not be a real thing that can happen in real life, but some people like to imagine it as a kind of special state where they can experience intense emotions and also be aware of what's happening around them, even in a deep sleep.
