I got this from a Ugandan blog. According to Google Translate, the bride who was identified as Betty Sserwadda was getting married to her prince charming, one Muwala Zubair in Uganda over the weekend when she lost her senses.
The bride and groom were dancing gleefully at their traditional marriage and suddenly, Betty began pulling off her clothes. It took the intervention of people at the wedding to overpower her and take her inside after she began her wired behaviour.
The blog says she hasn’t regained her senses since then.
