The signals from the trimeter can help identify which area in your room is a potential spot for further investigation.
You should look for cold spots or areas in your room. Just slowly move around in your room, 3 sqft at a time, sit down
on the floor and feel the air movement for about a few minutes in the given area. Make a marking on the spot if you detect
some coldness there.
Do the same if you have a trimeter and mark the spot where there is strong signals emitting from that spot.
There are a few possiblities that could explain your situation.
1. Your baji fengshui position maybe in conflict, you are not positioned in the correct and optimal direction.
2. Do you have a wooden bed or metal bed?
3. Do you have someone that you are very fond of but has already passed on.
4. Do you always travel out and in through the window?
What is the relevance of wooden vs metal bed?
