Dead people? Just one. I've been haunted since I was a kid. Things move and after awhile, I got to know when he was around. He's only been seen twice that I know of. Once, a neighbor sat across my kitchen table from me and told me that she'd slept with my husband and she was going to take my kids, my husband and everything I had, and there wasn't a damn thing I could do about it. She sat back, gloating, and then her eyes widened. She whispered "There's somebody in your house." She said there was a man standing behind me, through the doorway into the living room.
I knew there wasn't anybody there, so I asked her to tell me what he looked like. Young guy wearing jeans and a flannel shirt, just standing there.
Okay.
I asked her to leave and never come back.
She went out my door and fell down the stairs (I lived on the second floor, upstairs from a bar). She later said that she felt two hands push her, but there wasn't anybody at the top of the stairs. I was still sitting at the kitchen table. My hand to God.
After I called for help for her, I walked through my house. It was empty.
She never came back to my house.
The second time, I saw him myself.
It was many years later, long after I divorced that cheating sack of... you know. I was still smoking then, and my nightly ritual was to get ready for bed, shut off the lights, smoke one last cigarette and crash. I was sitting on my bed, about halfway through my final smoke of the day, and something caught the corner of my eye. I looked over, and there was a guy sitting on my overloaded basket of laundry, looking at me. There was just enough like coming in under the door for me to see a young guy with dark hair wearing jeans and a flannel shirt. He wasn't glaring or anything menacing. Just looking. He parted his hands like "What?"
I knew it was the same person my former friend had seen in my living room, knew it with the certainty that I know my own name.
We've all heard the expressions 'chill up your spine,' 'numb with fear' and how the hairs stand up on the back of your neck. But I only knew them as abstract notions before that moment. You can believe me when I tell you I had all three going on. I knew there were house-mates just on the other side of the door, all I had to do was call somebody. But I couldn't.
I darted a glance at the light switch to gauge how long it would take me to get to it. And, of course, when I looked back, just that fast, he was gone. I haven't seen him since, though I did feel him around me like always. One ex boyfriend insisted that there was no such thing as ghosts until he watched, with his own eyes, a soda can fall over, roll the length of the coffee table and stand itself back up. No lie. My children played with the family ghost when they were very small - though they scoff at the idea now - and I think he might have gone with them when they grew up and had babies of their own. I haven't had that familiar feeling that he's around for some time. I like to think that he is with them, watching over my grand-babies. I hope he is.
