I see it now.
If the sector the bedroom resides in calls for water, then place the activation in that sector of the living room, but generally you would not place water in the bedroom unless you've had a professional consultation and advised otherwise.
It is completely alright to bring a glass of water to bed with you.
Chunyi's general placing message water (water charged with a message) in the bedroom during the winter time and replacing the water every three days or less, isn't in conflict with Marie's suggestions, as well as most traditional feng shui systems, if the container is not a large, transparent glass item that says "water"as soon as you see it in the room. A small vase/container can hold the water and energy message without making an impact on the emotional energy in the room during sleep. I'll see if Marie has any insights on this.
Much Love, Shawn
