My daughter stayed with me recently, she said that she'd occasionally have nightmares and bad dreams and wake up crying.
When I asked them what they were about she said that she knew they were bad dreams because in them they said "sponsors Emmerdale" or "sponsors Coronation Street" in them.
She's only 4 years old, bless her. Sounds like too much TV playing on her mind to me.
My 6 yr old niece told me recently that she loves Eastenders and Hollyoaks. can't say i was very impressed as personally I think she is too young to watch either of these programmes. :O(
