That doesn't mean every time you see a dragonfly someone in spirit is there. The dragonfly or whatever it is would have to have special significance, or behave oddly in a way that it usually would not. Below is Story #1 of 4 about dragonflies and spirit.
STORY #4 - HER HUSBAND'S DRAGONFLY
July 12, 2016 at 7:59 AM
My husband's birthday would have been July 8, but he passed on April 4, 2016. I wanted to visit the cemetery that Sunday after his birthday, feeling drawn to do it with my recent loss. My sister-in-law accompanied me.
We sat on the bench in front of the family plot and started speaking about our losses, life and suddenly a dragonfly passed by. In a little while more showed up and then there was a swarm of them just flying around us but concentrating on my husband's and mother-in-law's graves (she passed 2 years ago). They didn't fly around any other graves, just those two and around us.
We sat and talked for more than 1/2 hour and the dragonflies never left us. There is no body of water in the cemetery that they would have been drawn to, just us.
I don't believe it was a coincidence. I believe it was a communication. The funny thing is that my husband never believed in such things.
MY REPLY: Whenever insects like dragonflies behave oddly, they're likely being influenced by spirit as the ones you encountered were. I believe that your husband was telling you he's a believer now!
