Can a mist build up in bathroom electrocute connecting to the bathroom ceiling light fixture or the wall receptacle (outlet)?

My concern is not fire since I take showers with shower curtain on and it does not splash that far, but my concern can it electricute if mist build up is dense enough or is there not a chance of electricution over the distance by mist build up? CONTINUED BELOW.....

I take a shower in a bathtub, behind a shower curtain, which I seal by water and the space heater is at another end of the bathroom, which is about 2 meters away and is behind a toilet bowl. Water splashing onto the space heater is impossible, but is electricution by steam/mist build up in the bathroom a danger? CONTINUED BELOW.....yahoo, really!?

From either the portable space heater or even from the light fixture? I also have two electrical outlets in the bathroom away from the bath tub. They have "doors" on them, but when space heater is in the wall socket the outlet's door is lifted to let the "male" plug in to connect the space heater. I think I did this once when I forgot to turn off the space heater, but I wonder if there is any chance of risk over many times doing this? Not water splashing, but I mean the mist build up.
