these kind of mice are called dab ntxaug (skinny ghost). I have no idea how they came up w/ the name... anyways in the daytime, they are in the form of mice but at night they become what looks to be "fireflies" flying around a fireplace. If you kill one of their kind, they will kill one of your kind. You should ask your parents about them.
Actually, to my understanding they could be in the forms many other things too. Cause my brothers were seeing a few different scary things going on while we lived in that house.
I've just asked my mom again about it the other day, and she told me the time it took from my brother being very sick to his death was not even three days. It was only like 1 day...it started today and by sometime tommorrow he was dead already.
She also told me, after we got out of that house, my dad still haven't ceased to underestimatin
g these spirits. He paid a few people to torned down the house and had them transfered some of the parts to be use on our new house. After we started living in that new house, my mom had a dream about two strange persons coming to visit our home. And they said to her, so this is where you guy are, we've been wondering where you guys have ran off to. After that dream, she started getting really sick in the same way as my brother and almost died too. She was pretty luck, her father was a shaman, he pleaded with the spirits and burned them a lot of paper money for them to leave her alone.
The people that came to built their house on part of that area left too after they lost two of their family members. But they did the same my dad did, they torned the house down and took parts from it to used on their new house also. After they moved into the new house, one morning the wife got up early as usual to cook and get ready. She heard loud stumping noises from outside like a Rhino running towards their house. She was about to peaked out to see what it was, then suddenly this big hairy and scary looking hand pushed itself through the wall made out of straws and hay materials. She was so scared, she ran to wake up her husband up but it was gone.
We were finally free from those evil spirits, not sure what happened to them from that point on.
