Sabbo pajjalito loko, sabbo loko pakampito.
The entire universe is nothing but combustion and vibration.
At certain times you will experience vibration at different intensities, not necessary limited to when you are sleeping. You should look at it arise and pass away.

This sounds like sleep paralysis, which often involves the following:
This is a common state that has nothing to do with Buddhism. In fact, some hypothesize that stories of alien abductions or succubi are distorted reports of experiences in that state.
Perhaps meditation may increase the incidence of this? One reported way of entering sleep paralysis is to remain conscious while the body falls asleep, an ability aided by improved concentration which can come with meditative practice.
To bring this back to Buddhism, if you are in this state, then you could try to induce a lucid dream by visualization and use that to practice Dream Yoga. You can also use the experiences you gain as insight into your daily life. With so much of life said to be illusory or dreamlike, experiences in this border state can be very illuminating.
For non-Buddhist stuff, you can...
Of course if you suspect that there may be any medical issues involved with this, then see a doctor!
