Lavender Sleep

I understand that lavender can be used as a stimulant as well as enhancing sleep.

Can anyone explain this apparent contradiction?

Evidently some need less sleep than others . Ms Denis’s annimation demonstrates that sleep is all in the mind……

「夢を見る」

see Gaëlle Denis

In English, we say somebody dreams or has a dream when they’re sleeping.
There is no verb in Japanese that is directly equivalent to the verb “to dream”.
When Japanese people describe a dream they either see a dream 「夢を見る」　or paint a dream 「夢に描く」.
