So i heard this

Maybe. I keep having dreams about my dog who died back in like 2012.

Gos either way.
What amazes me is how I can know people in dreams that I've never met.
Mix up locations and not realize it.
Dreams only become fun if you can realize while dreaming that you are dreaming.
It's fun.

I once heard a very loud fart from an old woman in a museum. She thought she was the only one in the room.

Yeah but it could also be bits of a alternate world where you can see them.

I had a dream where someone to whom I'm very attracted, and have dreamt about chasing in past dreams was very rude and dismissive of me. I probably had it coming, because usually when I chase him in a dream I'm flying through the air like a ghostly witch-vampire woman.

Anyway, later in the dream I was in a classroom somewhere trying to take a test for which I was unprepared, and I got caught cheating. At least in the end I met this very polite Japanese guy who would do pretty much whatever I wanted, so I made him carry my books and wait for me at my car. In my defense I was going to buy a translucent dress and take him out for a steak dinner, but then I woke up.

Could be... Unless it's a bad dream with someone who I definitely don't want to see.
