A friend of mine has a fleecy polyester dressing gown that she's had for years and suddenly, spots have started to appear on it as shown on these photos:

They've not all appeared at once but over a few days and not immediately after washing.
They seem to be in quite a regular pattern but I've not actually measured them to see if they are totally regular.
She's not done anything different to the item and the colour of the dots is not the same as the colour of the rabbits in the pattern, so I don't think it's a case of the colour having run.
We've racked our brains as to what might have caused this and would be interested to hear any suggestions - I think it might be supernatural ;)
