Creepy Whisper In The Night

I hadn't experienced anything paranormal for a while until about 2 weeks ago when I was woken up by movement at my feet. The touching manifested over the past few nights until I felt a tapping on my left shoulder which I ignored, followed by three hard, sharp taps on my head. I sat upright, opened the light and couldn't fall back asleep. Something had touched me and has been trying to wake me. It was around 3am once again, not sure if the timing is just a coincidence.

I've been getting my Mum to sleep in my room with me since, except last night when she fell asleep in her own room, so I got ready to sleep alone. It was 2am when I finally closed the lights to rest, when I heard a hushed and faint whisper. I disregarded it as my imagination playing up but the whispers got repetitive and much louder. I heard that of a childish voice calling out "mum." It called about 5 times until I opened my light again and ran into the kitchen. At the same time, I saw my (sleepy) Mum coming out from her room which is in the opposite direction of the house and we met half way.

Before I could open my mouth and tell my Mum what had happened, she asked me if I had called her. I said "No, why?" She told me she heard me in her room, calling out to her, that's why she had come into the kitchen. I told her that it wasn't me and that I had heard the voice too. Whoever it was, wanted us to sleep together and it seemed as though we were connected through this voice. Has anyone experienced something similar to this?
