I had woken approximately 01:15, got up dressed came out to kitchen put kettle on for a cup of coffee, turned on tv sat down. noticed a blue light through kitchen window, fanning from upper left to lower right of window.Kitchen blinds were half way up and open. first thought it may have been a helicopter but no sound, would have to have a few feet off the ground. the light was moving in a fanning motion at a shallow angle (10-15°) for what appeared to be a minute or so, they angle then changed to approximately 70-75° for approximately one minute when i observed a tall, very dark lanky and gangly being moving from right to left, being moved approximately 3/4 of window width, at which time i was getting up to go investigate unknown being in back yard. noted time on tv as 01:35am proceeding to get up when i noticed i was sitting back into couch and time on tv was 03:38am. blue light was still evident although being no longer visible. i got up went outside where everything was completely calm, still and no sounds at all. blue light had gone. looked around for a minute or two, came inside to get a cigarette went puts again where it was like someone having flicked a switch and all normal/natural sound had returned. came back inside, sat for hours going over occurance, no resolution, went to bed, having a hard time sleeping since.
