Fish like snake. Shpear and changing pool light from light blue dark blue to purple

Wasn't visable to naked eye, I picked it up with my camera it was a purple light that moved a way from me and then I was taking a video of our pool because the pool light was changing color and I seemed as if there was something coming out of the water fall, like a t st flopping I have been seeing strange shapes in the carpet like a snake frog squid and they are shaped the same way as the craft, I seen green lghts when my blanket would n 've and was in the shape of a snake (the cotton filing) and when I look a pcture there would t be a translucent image of a snake it has I also seen out of my bedroom window on the opposite side f the house semi lighted sky and the dark clouds stopped and saw a spo light circle of green with my naked a an I.couldn't get a video h cause my phone wouldnt charge.  My skin also stings where ever they may be or touched the shape are imprinted when in contact.
