These are all very interesting stories, but I don't really get scared easily.
This took place about a year a half ago. I had just moved into my home and many of my things were still in boxes. It's just me and my son. We were in the bedroom unpacking our things. My son was a year old at the time and he was sleeping on the bed. As I was unpacking our stuff, I heard a box being dropped in the living room. Being cautious I went out to see who or what it was. One of the heavy boxes that was placed on the kitchen table had been pushed off and was lying partially open on the floor. I checked the house and all the doors and window were locked. No windows were open. It couldn't have been someone who snuck in and left. I have hardwood floors and usually you would hear footsteps if someone was walking around. A couple of days later, while I was in the living room and my son watching TV. Another box that was sitting on the top shelf in our bedroom closet was pushed off. I went to check it out and like before, no one. So I said with a sigh...."ok, this is my house now. Leave us alone". It never happened again.
Another time, my cousin was visiting. He spent the night on the living room sofa instead of the guest room because he wanted to watch TV. The next day, while we were having breakfast, he swore that last night, someone was whispering or blowing in his hear. He got scared and without opening his eyes, he pulled the cover over his head quickly. Whatever it was, he felt like it was standing or kneeling right next to him, breathing right on to him through the blanket.
