Placing mountain picture above the headboard in any directions is effective in giving a person good sleep and support.
I find this method interesting because when one head is pointing toward bad direction , it can remove bad chi from bad directions and if one head is pointing toward good direction , it give strength and power to one's good directions.
Just my little experiences on bedroom mountain - hope it help.
I will like to share some feedback on mountain in the bedroom.
1. It had lower blood pressure for some - one reported it had reach a perfect reading 120/80 . - head pointing to health sector - West
2. Some don't have to go to bathroom during their sleep time anymore. Some how the mountain had strengthen the kidney or urinary bladder. Head pointing to health sector. - West
3. Some reported the noise from outside is very much reduced - head pointing to north.
4. Some reported that many part of their body pains is reduce or completely gone.
5. Some reported that their backbone pains is healed.
Generally most reported good sleep, feel safe and peaceful.
Picture size of about 5 inches will be sufficient.
