Psychic Phenomena

I was working through some garden photos I'd taken when I looked up and saw these weird squares hovering in front of the fence.  Obviously a psychic phenomena and ideal for today's Mono Monday hosted by Laurie54, 'silent letters' in this case the 'h' in 'psychic'.  I've added the original colour version as I think it shows it clearer.  After a while it disappeared. 

In other news: Maureen and Ian called round this afternoon for a cup of tea and a chat in the garden.  The weather has been very good, we had to try and find some shade it was so warm.
