Spirits are everywhere and as Buddha pointed out, it is one of the 3 lower realms. We reincarnate into the spirit realm due to strong attachments to many things such as our family, money, a place, food, drinks, anger, depression, and so on upon death. In this video, the spirit looks like it is attached to football.
Spirits have very little chances of learning the Buddhadharma because they are too consumed over their attachments. The only way for them to get out of the spirit realm is to wait for their karma to exhaust. This may take thousands of years depending on their karma. As my teacher always say, if we consistently contemplate on this, we will want to practise the dharma so that we won't reincarnate into the 3 lower realms and continue to be a helpless victim of our own karma.
