Deja Vu

Ever walked into a room and felt like you’ve lived that exact moment before? In this episode of I Didn't Know, Maybe You Didn't Either, BDhat dives deep into the strange and fascinating world of déjà vu. From brain glitches in the hippocampus to theories of past lives and simulations, we explore why this eerie phenomenon happens.

Speaker 1 (00:01):
How art thou be down here?

Speaker 2 (00:03):
And I like to kick off today's episode with a
big shout out to Steven Haral. He goes by Steve
horal Rally on Instagram and he sent me a DM
about last week's episode. You remember we was talking about mascots.
If you missed that, check it out. But he said
his favorite mascot is Scrody, the unofficial mascot of the
Rhode Island School of Designs hockey team. He loves it

(00:27):
because it was the most chaotic possible idea to counter
low game attendance, and despite being a mascot literally blocked
by safe Search, the school is just going along with it,
loving the expansion of the show. By the way, hey,
I appreciate that, Steven, and if you would like to
send us dms idk myde on Instagram with an underscore

(00:49):
before it and after it. But I said Scrody like
I'm childish, So I immediately thought it was like scrotum
and I told him that and he said, that's exactly
what it is. Y'all said me a picture of Scrody
the mascot. I'm not even gonna describe it. I'm just
gonna tell you that right now, this picture lives on
I D K M Y D E or an underscored

(01:11):
the front and underscored the back on Instagram. If you
would like to see scrody, it is ridiculous. I ain't
gonna cap I would go to a game just to
see scroty. But on today's episode, if I didn't know,
maybe you didn't either. Have you ever walked into a
room and saw something go down and thought, wait a minute,

(01:32):
I'd have seen this before. This already happened. It just
happened to me recently. At my son's state championship game.
He wins the state championship. I'm sitting in the bleachers
and I'm watching him interact with his teammates, and I'm like, yo,
I'm having deja vu. But then I thought, right after that,
why is it called deja vu?

Speaker 1 (01:53):
I didn't know. I didn't know. I didn't know.

Speaker 2 (01:59):
I didn't know.

Speaker 1 (02:01):
I didn't know. I didn't know. I didn't know.

Speaker 2 (02:05):
Now, first off, it says that a lot of the
brain activity for deja vu happens in the hippocamp that's
the part of the brain that's responsible for the memories,
like the librarian of your brain. So It made me think, first,
what's the other regions of the brain and what they do.
So you got the frontal load, that's like the CEO, right,
he handles the decision making, problem solving, and the self control.
Then you got the temporal load. Now that's the DJ right.

(02:28):
The temporal load controls the hearing, language and some memory.
People with temple load epilepsy they experienced deja vu more
frequently before their seizures. Then you got the parietal load.
That's the GPS of your body, helps you understand space
and movement, like when you stub your toe on the
end of the night staying you ain't even got to
look down, you know what it is. Then you got

(02:49):
the occipital load. That's the cameraman that controls your vision.
And last, but not least, of course, you got your cerebellum.
That's your choreographer, keeps your balance and your coordination and
check and I'm convinced my serebellum is own lag, but
my coordination is off like a light switch. So that's
basically how the brain works. And deja vu happens in
the hippocampus, and deja vu translates to already seen in French,

(03:14):
so we really shouldn't even be saying deja vu.

Speaker 1 (03:16):
It should be more dis yea vu.

Speaker 2 (03:18):
Now, it's like five different theories behind why deja vu happens.

Speaker 1 (03:22):
One theory is your brain just gets a little ahead
of itself.

Speaker 2 (03:25):
It's like when you get upset and you angry texting
and you just start texting the wrong letter. So all
the correct have to help you, but you're still seeing
what the in the group chat.

Speaker 1 (03:34):
Yeah, your brain does that too.

Speaker 2 (03:35):
One theory says, DejaVu happens when your memory and your
senses get out of sync. It's like your brain processes
that one moment twice. Another theory is your brain pulls
up a memory that kind of looks like what your experience,
but it's the wrong file. It's like you ask the
DJ to play some Beyonce and he hit you with
some Ashanti. Close but not quite. But the theory I

(03:56):
think is the most popular is the dream theory. That's
when you've been somewhere and you thought, bro, I dreamed
this exact moment. Scientists think dejah vu could be your
brain mixing up dreams with reality. But then there are
folks that believe that deja vu is proof that we
lived a past life comes from that feeling of familiarity
without explanation, right like when you experience deja vu, it

(04:19):
feels like you already lived that moment, but there's no
memory in this lifetime that backs that up.

Speaker 1 (04:25):
And that eerie familiarity makes.

Speaker 2 (04:26):
Some people think maybe I lived this before in another life,
and that ties into the concept of reincarnation. You know,
after death, your soul is reborn into a new body,
like a knight in Medievil.

Speaker 1 (04:38):
Times or an Egyptian scribe.

Speaker 2 (04:40):
Me I probably would have been a medieval janitor or
a gesture in the royal court. However, science leans more
to DejaVu being a brain glitch rather than a spiritual flashback.
But the idea of a past life is super fun
to think about. Maybe you were a pharaoh let my
people go, or maybe just maybe you were a pirate

(05:02):
or Liot.

Speaker 1 (05:03):
Black Beard on his bide.

Speaker 2 (05:06):
I'm interested in what you were in a past life
or what's your thoughts on deja vu? Is deja vu
spiritual or simulation? And to be quite honest, if my
life is a simulation, the programmer needs to stop making
me forget. While walking into a room. That's just lazy
coding on his end. Visit us on Instagram. I d
k m yde with an underscore in the front and

(05:27):
the back because did j'a vous being French for already
seen was something that I didn't know.

Speaker 1 (05:34):
Maybe you didn't either,
