How are people making these “teleported into another world” AI videos? (backrooms, SCP-3008, fantasy worlds) HELP pls

I’ve been seeing this trend a lot on TikTok where creators film themselves normally (selfie style, shaky camera), and then they appear inside fictional/impossible worlds like: • The Backrooms • SCP-3008 (infinite IKEA) • Dark Souls environments • Post-apocalyptic scenes with giant monsters The style is always “found footage” / Snapchat quality - shaky, grainy, low quality on purpose. The person’s face stays consistent throughout. I’ve tried Kling O3 (Reference to Video mode) but the output looks too cinematic / realistic. It doesn’t have that raw footage feel. My questions: 1.
