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.
Another thing: the size is 750 MB, which is relatively small. So maybe the audio is lower quality or the video is encoded with higher compression. Should mention that the file might have lower quality due to the size. Also, since it's a WEBRip, it's from an online stream and might have some issues like screen glare or lower video quality compared to a Blu-ray rip. Lucid Dream 2017 NF 720p WEBRip 750 MB - iExTV
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. I should also mention the release group, iExTV
