Being Held By a Supernatural Being

Two nights ago, my family went out of town and I stayed home alone.
It was late at night, the electricity in my house went out.
I lay on my bed playing with my phone.
In the midst of my busy life, there is one thing that really bothers me.
I heard footsteps outside the room.
In order not to be scared, I try not to care and continue to play with my phone.
My eyes are getting sleepy, I put down my phone and pull the blanket over me.
As I fell asleep, I was awakened by a firm grip on my leg.
For a moment I was silent and thought I was alone at the time, then who grabbed my leg?
I didn't dare open my eyes, my cold sweat covered my skin.
I was so scared and wanted to cry, but I tried to stay calm.
I prayed silently for my safety.
The rough hand touched the tip of my foot and suddenly my leg was pulled hard. I immediately screamed as loud as I could and suddenly the electricity in my house went out.
I was very surprised by my sight.
There's no one in my room, the figure pulling my leg isn't there!
I couldn't believe what I saw and felt.
I took my cell phone and called my friend whose house is not far from my house.
Not long after my friend arrived at my house, I told him everything that had happened and asked him to stay with me.
After hearing my story with strong conviction he said that it was a supernatural being, luckily I screamed at that time.

What do you think?
Was it really a supernatural being or just my hallucination?
But I'm sure it's real and not a hallucination.
