Confusion Of Vibrations

I have been confused about these vibrations since I was a teenager. I knew when my phone will be ringing. I could feel the vibration. I used to freak out my friends by telling them my phone will ring in a minute They would ask me if I set up a call? I would tell them no. They got freaked out about that. They asked me a whole bunch of questions and I didn't have any answers for them. It's cause I don't have the answers.

Same thing started happening again about 10 years later. My ex-boyfriend and I were going for a walk, he noticed I would put my hand where my cell phone is. Then my phone would ring a minute later. He asked me if I would expect any calls. Again my answer would be no. I just know when I will be receiving a phone call but I wouldn't know who would be calling me. He started asking me a whole bunch of questions like if I know what the meaning is of these vibrations. I told him I don't know anything about them. He wanted me to try these ex cerise of each vibrations. I really can't tell what they mean.

Sometimes without the phone, I can feel vibrations mainly on my right leg. The vibrations are usually really strong when something bad is about to happen. Like the time I was laying down with my son when he was a baby. His father came in drunk and he was ready to beat me up. It's like the vibrations were warning me or something. And the vibrations on my legs are coming back. I don't understand these vibrations. What do they mean? Can somebody help me with the vibrations?
