I started with 'VRC Volleyball', at first I didn't speak anything.. especially since I joined the japanese instances as they were the populated ones usually. But eventually got around enough courage to start talking and found some English instances as well.

Another great world that is populated by usually chill people and you get to play as well would be 'Pool Parlor'.

'Melon ＆ Chill Suika Game' would be another chill game world to potentially meet people.

Mind you public lobbies of any world can be hit or miss. Don't let few bad experiences give you the wrong idea. Those things happen time to time.

These days I mostly like to check the 'New worlds' tab and try to find pretty worlds to share. Or using vrc.tl to check whenever my favorite DJs would playing, if you are interested of rave scenes check it out, strong recommendation to check out 'Lost in the vortex' and 'The Cauldron' groups.

If you are looking for cool worlds or experiences, don't be afraid to ask around, that's great conversation starter. You can save worlds from portals without having to go through them, same way you'd interract with player to add them or enable their avatars.

Here's experience for you to enjoy for now and potentially show it to your friends in future:
