If you like snakes very much, that's all right. If the picture is not that kind of ancient painting, it is basically nothing. But it will stimulate desire and make people dissatisfied. No matter what, they will need more than others, and their mood will be more restless or irritable.
If people who don't like snakes hang such pictures, it goes without saying. When having nightmares, they are easily afraid of the outside world, unwilling to sleep, and upside down day and night.
