I don't know if imps can be called Toyol. But there are many toyols in my neighborhood. One is a regular visitor to my house every night. I have dogs and cats and this invisible visitor who makes a peculiar sound every night at midnight or after midnight asking for 'his food'. Which is apparently lighting a joss stick scent.
Just yesterday I had put his josstiick near the wash basin for easy disposal of the ash. But I forgot about the dhoop and went to wash my hand and it went off with sprinkled water touching it. Immediately, he sounded his 'need' again. So I lit the dhoop (jossstick) again and even opened my back door where he usually comes to receive the scent. He didn't object because he knows that I only open my backdoor to feed the puppies.
In another instance, these toyols (imvisible to the naked eye) which are no more than the size of a small monkey, take the opportunity to enter the kitchen area of every home to partake the freshly discarded food from the bin. The fresher the food, the tastier it is to them. One day I had just boiled some home-made remedies and cooled the contents for refrigeration. The left over was still warm and I had left my main door open at night. This guy came in without my knowledge. When I closed the door, and went to my room, I heard scratching sounds at the door as if the cat was scratching the door. But then I realized that the sound is from the inside and not from the outside of the door. It startled me. That was kind of first experience for me.
But these days, I sometimes miss these invisible beings when they don't come by. However, there are other ghosts in my house. They don't disturb me but help me my making sounds and coaxing me to get up . When I do get up I see that I have not locked my main door or my car. When my daughter came by with her kids to spend her weekend at my place, she was supposed to stay two nights but cut it short to only one night. So told me of disturbances like a man disturbing her while half asleep. In the morning she asked me if there are entities in this house, I said YES. The same thing happened to my friend who put up a night in my house. He told me of being unable to sleep like there was a presence.
But you know, they don't bother me and I know they exist in every house even in the Gurdwaras.
