Have you ever witnessed something paranormal / unexplainable?

No. But I desperately want to.

I have had that sleep paralysis thing before. It really does feel like something is holding you down. And it feels like something is in the room with you. Freaky deaky shit.

Oh yes many times in my place. The ceiling cover on one of the evaporative cooler vents ( kept in place by magnets ) would explosively fly off and whack against anything in the way of it with such force that it broke off one of it's corner edges. This would happen even on a still day. Perhaps it was due to temperature differences and a build up of relative air pressure but none of the other vents would do it and this thing would fly off even in the middle of the night with no heating on.

An even weirder one was the man-hole cover in the laundry being lifted up and half displaced back into the roof cavity. I heard it thump and went and checked it out immediately and there was no-one up there.

As for strange sleep occurrences I used to be known for falling asleep with my eyes open and when that happened I could have dreams that took place in my physical surroundings. So I would see "ghosts" moving around and about me. I have also been physically shaken awake from sleep by "ghosts".

No, but you made me think of this:

Many years ago I was swimming at some Oahu beach and heard this soft rattling or clinking noise. It was kind of spooky. An acquaintance I was with then related some story in Hawaiian mythology about sea turtles and that the sound was somehow related (I don't recall how).

I went back in the water and discovered the sound was the chains of marker buoys rattling as the water rose and fell. When I went back and told him, he just shrugged his shoulders. He wasn't trying to pull my leg.

Once I was asleep, alone, in my bedroom. I had the feeling that someone was in the room with me.

I opened my eyes to see a small woman, around 45 years old, standing at the end of my bed, holding the closed curtain as though she was looking out the window. Her eyes were a crazy shade of light blue.

I blinked and she faded away. It was weird, just a dream. Weird in that my dream took place in my bedroom.

So I went back asleep. Later I started to wake up with the exact same feeling. Someone was in my bedroom. I opened my eyes to see my bedroom door open, but closing. I looked at it expecting to hear it bang shut but it closed without sound. I stared at the closed door and realised that in the 'real world', it was never open.

I felt like twice that night I had glimpsed the spirit world that was taking place around me.

I've seen a pair of boomerang looking multicolored craft floating over a local lake...I may be nuts but my Dad (A pretty sturdy retired Cop and NOT a guy to talk bullshit swears he saw the same thing with his second wife on the Taconic Parkway)

The Hudson River Valley UFO sightings were a really weird deal!

Yes. One time, and it's messed with my head since whenever I think about it.

Early 2000's.. my friend and I went to this car dealership that used to be near our high school and had been there for decades. My buddy wanted to ask about an old Chevelle in the parking lot. This older guy comes out and starts talking to us, and eventually goes back in. My friend had more questions, so we eventually went inside as well.

As soon as we stepped in, my whole body just froze. The inside of the shop looked old.. like everything inside was from a different decade. There is a younger guy at the counter reading, and the older guy was nowhere to be seen. My buddy starts asking him questions about the car, and the dude acted like we weren't even there.

Eventually he looks off to the side of us and says something. I couldn't make it out, but it was like he was talking to someone who wasn't there. My friend and I looked at each other confused. and I was just like "let's go dude" because the whole thing felt off. He agreed.

Fast forward years later, I was having dinner with my dad and his friend, and he brings up that dealership. Apparently he knew the guy really well that owned it. I asked him if he had a son that worked there, and the guy said he never had a kid. But the guy in the store looked exactly like a younger version of the older guy in the parking lot.

Even thinking about it now it was like we stepped into a time warp or something.. I don't believe in that stuff but I get the weirdest feeling when I think about that day.

No, not that I know of. I'm reasonably open-minded to the possibility that there's more going on than meets the eye, and I've known people who swore they had paranormal experiences, but I've never had one that I'm aware of.

An ex-girlfriend of mine, who's the serious type and not likely to make things up for laughs, told me about three paranormal experiences she believed she had.

One was at a cemetery. It took place during Obon, a Japanese Buddhist holiday for honoring the spirits of the dead. My ex and her family went to visit her grandpa's grave on Obon, and while they were there, the car, which was empty, locked and didn't have the keys in it, started flashing the headlights on and off repeatedly. My ex's family believes it was the grandpa saying hello.

The other two took place at her grandma's house in Tottori (a rural prefecture in western Japan), which she believed was haunted.

My ex told me that when she was little, during a visit to that house she saw the ghost of her grandpa (I think it was her other grandpa, not the one from the previous cemetery story, though it's been over a decade since I was with her and she told me this so I can't be certain; I just remember that both of her grandpas had already died when I knew her), in his World War II Imperial Japanese Army uniform.

On the other occasion, during a different visit to the grandma's house, my ex was asleep when she got woken up by a sound like a cat or something was walking around in circles in her room. Over and over and over and over and over, in circles without end. They didn't have a cat or any other kind of animal, and though a wild animal could have gotten in the house, walking in circles around one room endlessly would be strange behavior. My girlfriend was too scared to turn around and look where the sound was coming from, and eventually she fell back asleep after an hour or so of listening to this. When she woke up in the morning, the sound had stopped and they didn't find any sign of an animal in the house.

I can't swear to the authenticity of these stories as paranormal experiences; all I can say is that my ex definitely believed they were. I would have liked to visit her grandma's house out of curiosity, but I never got the chance.
