I should also mention the release group, iExTV. If it's a known group, but if not, just state that it's distributed by them.
Let me check if there's any other possible meanings for NF. Could it be "Not for Profit"? If the release is non-commercial, that's a thing. Or maybe "North Fork" or another regional thing, but that seems less likely in this context. So probably safe to go with the standard torrent tags. Lucid Dream 2017 NF 720p WEBRip 750 MB - iExTV
NF might stand for "No Film" or "Not for Profit", which in some contexts indicates it's a non-commercial release. Alternatively, in torrent terms, "NF" could be a flag, but more commonly, it's "No Film" which means the source wasn't a physical film—like from a web stream rather than a DVD or Blu-ray. So I should explain that. I should also mention the release group, iExTV
Also, the title "Lucid Dream 2017" might be a bit confusing because there are two versions. Need to clarify which one this is. The 2017 version is a horror film, so the description should reflect that genre and plot. Could it be "Not for Profit"
