Is it possible for any kind of human beings to have a power to communicate with ghaibs such as jinn or those who has passed away, because in my country, there's a very famous youtuber that make a video about "interviewing" those who has passed away. The youtuber will make so the deceased's soul enter one's body, after that, the youtuber will start asking why he/she passed away and why he/she is still in this world not going to the akhirah and it doesn't like it's a gimmick or a lie, the video seems so real. Would you mind to explain about this? What actually happens?

Yes it is possible, but doing such acts is haram. You may see this video for more information on paranormal activities:
