There's at least one vampire in Scotland who's afraid of blood, reports SkyNews.

Marianne Sellar, who played a vampire in the horror tour at the Edinburgh Dungeons (search), was about to bite into a victim planted in the crowd when a foreign student tapped her on the shoulder and told her she had a nosebleed.

Sellar promptly fainted. She later admitted she had a lifelong fear of blood.

"It is quite embarrassing," she told the Daily Mail. "I had managed to keep my phobia a secret for three years because normally we only deal with fake blood, which I can handle."

"When the visitor showed me all the real blood," she admitted, "I just collapsed."

Sellar, 24, now performs a different job at the popular tourist attraction. Another actress is being trained to take her vampire role.
