'Hollyoaks' actress Claire Cooper is a chronic sleepwalker.
Claire - who plays rough and ready character Jacqui McQueen in the Channel 4 soap - says her slumbering affliction would stop her from appearing on any fly on the wall reality TV shows.
She said: "I sleepwalk and talk in my sleep, so I wouldn't do 'Big Brother' for that reason alone. If I'm really stressed about something it happens. I get up, go for a walk, maybe have a conversation, that sort of thing.
"I'll be convinced I'm awake and I'll explain to people that I'm not asleep."
Claire also says that behind the scenes on 'Hollyoaks' she is a prankster and always setting up jokes to play on fellow cast members.
She added: "We do play a lot of pranks on each other. I'm more of a prankster, but I tend to get wrapped up in other people's pranks.
I'll often instigate an idea and then I'll get someone else to do it."
