The first occasion was when I lived in a small two bedroom apartment. I was just learning about all the different types of ways to prove a haunting like pictures, videos, evps, and personal experiences. I was sitting at my computer in the spare bedroom listening to different evps with a headset on. My dog who was a 1 and a half year old boxer was sitting next to me so I decided to unplug the head phones to see what her reaction would be. I played three or four evps and she just sat there wanting to be petted. Then I played one of a little girl in a graveyard that said "I want to go home". As soon as she said it my dog knocked over a chair trying to leave the room so fast. Then she wouldn't come back in until like three hours later.
The second was like a week or so later. I was lying in my bed on my day off trying to decide if I should get up or go back to sleep when I heard what sounded like a whistle. So I opened my eyes a little wider trying to shrug off what I just heard as coming from outside. Then it sounded like someone said my name from my door. This scared me a little considering I was facing the opened door and no one else was in my apartment.
I got out of bed and decided to clean up the spare bedroom. While in there I noticed my dog wouldn't come past the doorway even when I called for her. She just kept staring at the area above my head. So I turned around to pick up a piece of paper off the floor when it felt like someone pinched me on my butt right where my wallet was. So I looked at my dog thinking that she had finally came in and was trying to play bit me. She was still at the door and now she was following whatever she was looking at to the corner of the room where the closet was.
It didn't really freak me out it was just a weird experience.
