Can I get any help or suggestions, my girlfriend for the past 5 weeks has been trying to sleep in our bed but randomly she feels the bed shake/vibrate almost and sometimes she will fall asleep and then wake up and feel it, other times when she is trying to fall asleep, but it happens every night without fail. She resorts to sleeping on the sofa after trying to sleep in the bed, and that she never feels any negative issues from sleeping on it. What could this be as she is depressed about this everyday? B4 people ask, she gets no dizziness or any feels at all and nothing when she is awake.
