Are the dragonflies considered good luck when they hang out around you?

Don't know about the luck part, but we had quite a dragonfly show the other night. Two things unusual. it was dusk and we live in town--no ready water source! It flew up under the porch,then down really low through the flower beds. It repeated this cycle several times sometimes dive bombing our cat or flying up towards me and averting at the last minute! At one point, he flew smack into the post on the porch and we thought he might be dead but after a few seconds we heard his buzz and off he went again! After a couple more laps, he just flew off and was gone! What fun while he was there! There WAS a full moon that night.crazy things happen with a full moon!
