Odd reoccurring similar dreams?

Normally I wouldn't be so stuck on dreams because I largely don't remember them and they don't normal repeat. Though this one keeps repeating so it confuses so some help with understanding it would be appreciated.

Basically I keep having these dreams though the events and interactions are largely different but they're always the three same people in them though there are also others but they're not in all the dreams unlike these 3 and every time in the dreams we're all stoned or getting stoned.

2 of them make sense because I've known them both for a long time I'm personally quiet close to them in RL and in the dream. The other person though really stumps me why they are in my dreams. Plus the stoned thing makes sense coz I've smoked a lot of weed with the other 2 over the years.

Though the 3rd person really stumps me why they keep showing up in these dreams. I know this person on a less then associate level. You know someone you know but don't really know and they're kind of in the background like some person who may work under the same company as you so you occasionally see them walking around but you don't interact. Which kind of makes sense in the dream but doesn't really at all. In the dream we don't interact for no real reason in fact I don't think the other 2 even interact with them which makes sense. However in the dream despite no interaction they're not in the background. It's like it's this unspoken thing that they are part of group and on same level of
