Oh I have! And I wrote a shortform about seeing something - not sure what - one of the other writers who has also commented on this post gave me an excellent interpretation that put a whole positive perspective on an otherwise nasty 3 am experience - I hope you are able to get your nightmare free sleep back soon - I know how it feels to wake up at 3 am and unable to go back to sleep - I just grab my laptop and start typing away - some of my best posts have been the 3 am ones :)
