Just a weird dream last night - Hayling Island

I was walking down glazed terracotta steps in a narrow passageway which appeared to lead to floors in a parking garage, there were damaged cars visible, a woman walked past me holding an umbrella as it was raining really in torrents, everywhere was wet with water just flowing a great rate down these steps while i was trying not to slip on them, and she said

did you know 500 people died at Hayling Island in Hampshire this morning?



I never think of Hayling Island, never been there, wouldn't recognise it if I saw a photo of it.
