Why do people put a glass of water under their bed?
Simply so, what does putting a glass of water under your bed do?
A glass of water by your bed and level with your head, will absorb negative energy if you are having trouble sleeping. Throw the water down the drain in the morning to flush away the negative energies absorbed. If you can't move the bed, its best to close the door. Do not have your bed placed directly under a window.
Also, what does water under the bed mean?
You need to place the glass filled with water under your bed and leave it overnight. If it has either of it, then it means that the negative energy has been absorbed by the glass of water. On the other hand, even if the glass is clear and the water is not so bubbly, it should have absorbed the bad vibes.
For the beginner, simple is always better. And when placing that glass of water upon your altar/shrine, dedicate that glass of water and that candle to God, your guardian angel, and spirit protectors so that you do not attract any other unwanted spirits that may be hanging around at the time.
