Personally, I believe spirits exist. But I can't see spirits, and I'm rather glad I couldn't.
There are quite a few people in the world who call themselves “psychics,” but there are many cases where they are “self-proclaimed psychics” until they get tired of it. Even if they are psychics, they are counselors who perform a performance called Hotokeoroshi and solve clients' problems. After listening to the client's concerns, grasping the client's recent status, family situation, etc., solutions and improvement measures are conveyed in the words of the deceased. http://hasunoha.jp/questions/3531
Among the hasunoha questioners, it seems that there are occasional people who seem to “really see” due to their high reception function.
It seems that it is impossible to tell others that spirits can be seen, but it seems that there are also cases where efforts are being made to interact with people who have died. However, it seems that there are cases where people feel burdened by receiving the voice of spirits. http://hasunoha.jp/questions/4752
Also, among those called psychics or psychic mediators, there are people who say that God or Buddha “descended” and “dwelt” within them. It may be something to be thankful for, but for the person in question, it is rather full of anxiety. That's because God and Buddha don't have instruction manuals.

Even if these people can really see spirits and gods, they cannot unequivocally determine whether this is a good thing or a bad thing. The reception function is too high, and I think it would be very difficult to have a spirit in front of you regardless of the time and situation. It's fine to wish to interact with spirits in fantasies or delusions, but I think interacting in reality would be burdensome.
