I think it has something to do with memory and it's relation to the perception of time passage. I once read somewhere the brain marks the passage of time by "noticeable" events, that's why if you watch a pot of water it seems like it'll never boil. Benzos fog up the memory, mostly without you realizing it. I think that's what warps your sense of time. If that makes any sense haha.
Yea i guess that's what it was, i kept day dreaming, i usually take them at night so i dont really notice it because i end up asleep after a hour, but then again at night i take like 3mg so im pretty high when i take more than 2 mg
