When Cartoon Characters Become Mermen

Happened on June 17th, 2014:
All I recall is Gumball being a merman, nothing else.

Guest star from Hungary

Happened on November 15th, 2013:
I was playing with candy that looked like medications and I was watching Cartoon Network at one point. It was CN HQ. The channel was airing a promo for a Ben 10: Omniverse sweepsstakes competition (in Portuguese and English). From my bedroom's window, I could see people cosplaying as Disney princesses from a large gray ring with four strings coming from the ground. The ring wasn't good, it wasn't of the best material.
Guest star: Ákos Abonyi (Ákos97HU from the Toonzone forums), which was mentioned for a while, don't know why.

Random dreams from May 2013

May 14th: I was checking my EPG and Channel 67 (FX) was labelled as "Fish Hooks" and Channel 68 (FOX Movies) was labelled as "Fishhooks". That's what you do when you watch too much FH fanart two days earlier.
May 15th: In this dream, there were plans to close down CNN, and later, I was watching what turned out to be the last ever episode of Phineas and Ferb. In this episode, literally EVERYONE in Danville except for the platypuses all became merpeople.
Later I went to the weirdest KCA ever, hosted by Josh Duhamel (host of that year's KCAs) as a merman in the style of Darwin the Merman. The building where it was set was a cross between Walt Disney World and the Wig *cough* Sun *cough* Sphere in Knoxville, Tennessee.

Ben 10 as a merman?!

Happened on April 18th, 2013. This dream featured me watching a weird episode of Ben 10: Omniverse. It involved Ben, stuck in the middle of the sea, as a merman, with no Omnitrix and was in a "help me" situation.
Turns out that it had a little backstory: Ben teamed up with a scientist to duplicate him (without the Omnitrix), however things weny awry and it turns out that the duplicate was a merman. The "merman Ben" should have an Omnitrix of his own with ten undersea aliens, but there's only one of them I know (Ripjaws) and it couldn't get to reach ten.

Generator Rex in EU-PT

It happened one Saturday morning before waking up in November 2012:
It was all pretty normal, however the TV was on RTP 2 and it was airing an episode of Generator Rex.
It was dubbed into Portuguese, and they never had enough budget to make a dub for it.

Juniper Lee while walking

In November 2012, I had a dream where I went to someone else's house with my mother. I was listening to the theme song to The Life and Times of Juniper Lee on the way there, as we were walking.

I got in and it had a bridge as we got in there. The living room had a lot of books and the TV was tuned to RTP 1.

October 2012, part 3: CHECK it.

I was walking at my building and then I noticed that there was an apartment with CHECK it. designs. I got in and the lobby was all CHECK it. themed, there was also a shower. I later explored some weird territories full of floating neon lights.

October 2012, part 1: In the supermarket with Ben 10

I went to Braga Parque and entered their Pingo Doce supermarket, however it looked completely different from real life: it had lots of blue and yellow neon lights, the place was so dark but the lights were abundant. Ben 10 was there (the original Ben). I was hallucinating of sorts.
Then the supermarket changed from one day to another and turns out that I left a Continente supermarket.

Mermen eat carrots

In April 2012, I had a dream where I was listening to a song about carrots that looked like the mermen song from the last episode of Flapjack.
OFF: Here's the mermen song:
"OOH
We are the mermen, our bodies are tight
We work out all day and we wrestle all night
If you want to get buff, there's no time for sweet stuff
We just broke our window, 'cause we're not too bright
We are the mermen, we're not too bright
mermen
watermen (?!)"

FHFIF in EU-PT

It happened in August 2011. I was watching TVI at the living room. I noticed that FHFIF was airing. I only remember scenes from the intro, not the dub that I've seen on my dream.
That same month: I was walking near my home and I noticed a strange book fair in the middle of the street.
Later on, I had a dream where I was checking my EPG and Cartoonito took over CN HQ's morning schedule. This happened in September that same year.

Some of the oldest dreams I remember

2002: I remember going to my city's Segurança Social (=Social Security) center, and Santa was there. Weird.
Fall 2003: I was at someone else's home, and I was watching Codename: Kids Next Door. The episode ended (as usual) and it went to the end credits. All of a sudden, as soon as the credits ended, it cut to a blue screen with a yellow stopwatch, resembling the menus of a TV from the late 90s. It later went straight to the Curious Pictures logo.
around the same time or year: I was walking, alone, at age 5. I came home and noticed a strange Curious Pictures logo which had a green barn (or something like that) with a green chicken, a yellow chicken and a red chicken, with the text underneath.
April 2004: I went to a CN website (CN UK's?) and the website had a loooong intro with CN characters doing random dances set to some song I already know but don't know anything else about it. It repeated at the end and it took me to the microsite of a KND marathon with special, live-action guests between the episodes.
September 3rd, 2006, the day before My Gym Partner's a Monkey premiered on our screens. I watched it and the theme song on my dream wasn't "I used to be in a human school where everyone was the same, now I go to an animal school 'cause Lyon's my last name", it was more or less like a Latin American telenovela. I was also trying to fly with a fan turned on.
October 2007: I had to save my school friend at the time who became a mermaid, stuck on a sandbox.
Late 2007: The first time I turned into a merman on my dreams. I had a green tail (?!) and I was at a bouncing castle.
Unknown date: I went to an electronics store (Worten at Continente Modelo, then known as Modelo) and it looked like an aquarium with humans. No merpeople involved.
