Is there really a ghost in the Heian era in Japan? Is it true that ghosts travel at night?

This is just a legend. Japan's Heian period is a dark and unknown era, and both humans and monsters are * * *. The place where monsters live and the place where humans live actually overlap in space, but humans move during the day and monsters appear at night. This feeling can be seen in Miyazaki Hayao's film Spirited Away (also translated into Spirited Away and Hidden Girl). Although the theme park that is deserted during the day has become a deserted market, at night, when the lights are on, monsters appear one after another. At night when monsters haunt, they live the same nightlife as human beings and are very lively. At that time, in Kyoto, the whole road was empty at night. At this time, there will be many grotesque monsters, such as the procession of temple fairs, which are ferocious and are called "nocturnal ghosts", and some are like broken teapots, pots and pans, marching in the streets at night in droves. It is said that those who witness them will be cursed and killed for no reason.
