The previous comment is still correct: even without weed we dream a lot and don’t record most of it.

Alcohol in our system at bed time impacts sleep as well. We’re consciously at rest (or blacked out from over consumption if that is ones thing) but our body is busy metabolizing.

Poor signal, YouTube isn’t loading. Not sure if the clip is similar, but as I understand it recording a dream and restless sleep from metabolizing substances are separate processes.

Indeed, in general we are not aware of how much we dream, because we don't remember. I should have specified better.

Weed and alcohol specifically suppress REM sleep, where most of dreaming happens.

Suddenly stopping weed or alcohol leads to a REM rebound, and people experience very vivid dreams. This association suggests they were actually not dreaming much before.
