OK, I just had to start this:
What are some of your crazy stories of things you saw, which, though not necessarily bad, made you think "WTF?", i.e things you just never had any life experience to suggest are possible?

Here's one from today:

I visit the transfer station (dump) near me all the time looking for lighting stuff and whatever else.  I live in Fairbanks, Alaska and right now it's home freezer temperature outside, about -5F.  Somebody dropped off a bunch of bread and other food items I don't and frankly don't care to remember in the reusable items area.  It's cold enough outside it won't spoil, but I'd just never had any experience to suggest such a thing was possible and thought "WTF?!"

What are some of yours?

When I was going back to Reading from London there was a tall fit looking man who was topless and he was rapping to his iPod/iphone to some of his tunes and therefore gave me and some passengers a true sight!!!

There's a store near me that's being renovated. I wanted some old ceiling fans from there (Hunter originals). When I went to go ask for one of them they told me that they scrapped them all. I cried for about 2 hours. Then the most unexpected thing happened. [I passed by the building one night and I saw them relocated . glow] I'm happy that they got relocated and didin't get any. If I did get any the rest would be scrapped

How about when I saw that viral post on Reddit mocking LG? 

What one? I don't use Reddit.

If you need more WTF in your life, search "Black friday 2016 fights and deaths". 

One time i stepped on a C6 christmas bulb in just socks an it didn't hurt my foot

Here are some more I should add:
1. One time when I was on my computer in my room, the pull cord on the window blind just randomly started swinging as if something had hit it

2. My computer and monitor turned on by themselves one time in the middle of the night

3. I was testing a metal halide lamp, when it suddenly goes out then restrikes 4 seconds later. It was at full power and shouldn't have been able to re-strike that fast (it was a 70w metal halide lamp)

@Zarlog:
Your house is haunted

Probably just the other nite. It was around noon at night here and I was drifting to sleep. Suddenly I hear a few weird voices coming from the kitchen. I look over, the door is locked and I can't see anyone obstructing the lights on the appliances. I'm staring over there when I hear a widower voice call my name twice, then a THUD, and then the fridge kicks in suddenly sounds odd, like an industrial sized compressor and a fighter jet and with a bit of a metallic grinding. I never heard the fridge make that noise before then, and it hasn't done it again yet.

Mannnnn do I have a great WTF story for you guys. It's funny because I was going to make a thread talking about this, but
since this thread is about weird stuff, I figured I'd bring it up here. I had one of the STRANGEST dreams I've ever had in my life,
just a couple of days ago. (May even vlog about this someday) I was walking around inside a lit but completely abandoned Kmart.
(I've got absolutely no idea how I ended up in there, or where this Kmart was even located.) Despite it being my dream, the Kmart
was completely lit with T8 lighting much similar to what we see today. -_- Anyway, I kept walking around and all of the sudden
a random floating medium sized fish that looked a lot like Marlin from Finding Nemo, floated my direction, stopped, and looked at me
with wide eyes. "Are you sure you want to die?" It said, with a shaky voice that sounded like patrick from spongebob. Then suddenly everything
went dim and there was a Yes< No, option. I panicked and tried to move the arrow that was pointing to the yes towards the no with brain power, but I
had no control over it, and the arrow randomly pointed to the no option, but then quickly back to the yes. The yes option got selected
despite my efforts, and everything slowly went dark. That was the end of THAT dream. Although I'm a little weird at times, that dream was
beyond my level. Waaaayyy beyond my level.

You dreamed this tonight ?

Possibly at the very same time, on the other side of the world, this was broadcast on TV :

You sure that was a dream? That's some horror game stuff there.

Yep, that was a dream. Incredibly weird and unforgettable, but it was thankfully just a dream.
Of course I was freaked out during the dream, but looking back, I think it was absolutely hilarious.
@Ash, this was a couple nights ago. It was almost like that scene in Pokemon, only much more sudden, creepy, and strange in comparison.
