Emotion in dreams; erratic sleep

Typically, I am unusually emotionless in my dreams. At most, I will feel tension while infiltrating one of the facilities of the alien invaders. To take a couple of recent examples from dreams, when my passport was stolen shortly before a trip, I was simply irritated and made a mental note to call the consulate about emergency travel papers. And, when the curtains closed before I got there to close them, I merely wondered if I were unexpectedly telekinetic and had a go at consciously trying to remotely close the curtains in the next room as I approached those, which didn't work. However, last night, in a dream that involved my helping to keep some practical issues straight with our time machine, when we were a few decades back in the past, I was briefly overcome with emotion when asked if I might wish to contact anybody in that time period.

I may be remembering more dreams because my sleep has become irregular. I suspect that I am coping worse with external influences on my schedule. I fall asleep easily but don't sleep the whole night, instead taking a supplementary nap rather later on.
