why is it dangerous to sleep in a closed room where a lamp or fire is kept burning?

A lamp or fire has flames which require oxygen for combustion.
In a closed room, oxygen does not refill as there is limited oxygen available.
When the lamp/fire takes up all the available oxygen, it gets used up and there is no more oxygen left in the room, which is very dangerous for us as we might not be able to breathe.

Explanation:
A lamp or fire used oxygen in the burning process. In case of closed room there is no regulation of CO2 and O2, so co2 released in burning process fill up the room by utilising oxygen in it.
And it caused death.
