Who else is lingering in my heart when I can't sleep at night? Holding the lights and bamboo curtains, swaying with the wind in my dreams, what does it mean?

I can’t sleep at night: I can’t sleep at night

Who is still lingering in my heart: I still miss someone in my heart

Lights and bamboo curtains sway in the wind in dreams: I dreamed that the lights were on and the wind was blowing the bamboo, as if someone was coming.

Full sentence meaning: I missed someone and couldn't sleep well at night. When I fell asleep, I seemed to see the lights on and the wind blowing the bamboo, as if I missed that person.
