Couple go into a trance on their wedding day... video

A trance is a half conscious state where one is unresponsive to external stimuli. It can also be categorized under hypnosis.

So, this is the video of a Nigerian couple on what seems to be like their wedding day, going into a trance.

Here are the questions I have:

what are your thoughts on trances? Do you believe in trances?
Is it normal for Christians to experience this?
Does this only occur in Nigeria and other developing countries as spiritual situations like this have been tagged to developing countries or it can also be traced to developed countries?
