i did a TON of lucid dreaming and eventually one guy shows up that doesn't listen to me or do what i want. seemed like after i did enough damage to the narrative by flying around or killing off dream characters for no reason this same dude would show up, always from far off too so I'd know he coming. and when he got up to me he would just wrestle me down and prove I wasn't in control. all felt real to me and it happened in dozens of different lucid dreams.
