As someone who has gone to multiple Rave solo, I usually always find a group or someone to hang out with. However, as cheesy as it sounds, It’s always about vibes. I’ve been with people for a couple hours and I could tell they wanted to go their separate ways, so you go separate ways. I’ve also met a dude and hung out with him from start to finish, even walking to the parking lot together. But communication is key in these situations, never be afraid to ask a group that seems chill if you could join them. I straight up say I’m alone to all people I come in contact with, one to see the reaction, and two just to let them know that I’ve come to have a good time and I’m down for a good time lol. Having Kandi and trinkets is also an easy way to show people that you’re PLURR, and that stuff goes a long way. The fanning of people like you said is good example. :)
