Welcome! This is the right place to share dreams, for sure. I also looked for an online community after my first successful LD that I kept together longer than a few seconds. I shared it with my dad right after waking up, but he told me I was lying and lucid dreaming isn't real.

I haven't had shared dreams yet, as far as I know, but I've had dreams that sort of foretold future events. I do not easily accept that dreams hold some sort of mystical power to connect minds or tell the future, so I'll wait for more experiences before changing my mind. But there are people on this forum that report sharing dreams, so I'm sure you'll find like-minded folk.

See you around!
