Wooden bed frames are made from wood and wood comes from trees.
Some trees have spirit in them, people who believe in tree spirits would
place offerings and sometimes ask for 4D numbers to those trees that
are being identified.
It may be possible that your wooden bed frame were cut from the tree that
had spirit dwelling in them. Its "possible"that spirit is now dwelling in your room.
Your situation may be quite severe, you maybe losing a lot of yang chi, the male essence.
If you do not resolve this problem you may slowly become weaker gradually and would fall
sick very easily and feeling listless upon waking.
Sleeping is to help your body repair itself and revitalizes it, so you should be waking up feeling energized.
So something is not right.
It is also possible that a spirit is trying to zap your yang chi and take you away.
Also be very careful with the window, make sure the grills are secured and locked.
It seems that you are not in control of the body and your consciousness, you could
be easily influenced by the spirit to fly out of the window physically.
Its trying to condition you to get used to traveling out the window.
You should start protecting yourself by placing objects or symbols of protection on the window area
based on your own religious belief.
