Srimath Varavara munaye namaha

Swamy, generally people say if lizard sounds/ hisses there will be some god or bad effects based on the area in home.
Also people tell different fruits(பலன்) for lizard falling on different parts of the body. This was even mentioned in certain calenders.

Some say this was mentioned in a sasthram named gauli sasthram.
Is this just a superstitious or real thing ??

Needed clarification 🙏

Adiyen Varavara muni Bruthya dasan 🙏
