GUSSU-RI ぐっすり
Meanings
The state of being deeply, well, asleep without any interruption.
Examples

昨日はぐっすり眠れたので、今朝はとても気分がいい。
・I gave him some medicine, so he should be sleeping soundly by now.
薬を飲ませたので、今頃あいつはぐっすり寝ているはずさ。
Dogmatic Opinion
Whether it’s healthy sleep or drug-induced compulsion,
a little external stimulation won’t wake them up.
But there is an image that will surely awaken one day.
Therefore, it is not used for unconsciousness in intensive care units or
for people who have died.
