drifts off

Nestled beneath the silky folds of her lilac satin sheets, she drifts off into the mysterious world of her imagination.

在她身下方是有着丝绸般褶皱的淡紫色的床单，她在梦中想象飘落到了一个神秘的世界。

She went like a small boat that drifts off into the night on a calm sea.

她走了，好象宁静的海面上消失在夜色中的一艘小船。

In meetings he sometimes reads from notes and "drifts off" .

有时候开会期间他会看笔记然后“昏昏欲睡”。
