Is it wrong that I used to be scared of these 2 things my sisters scared me with?

Ok so for anyone reading this, it might be long so yeah.

Anyways, back in the summer of 2007, a show called Robot Chicken (you guys know that show right, it comes on cartoon network's nighttime block adult swim) had a 2nd season released on dvd. My mom loved that show, so she bought it. I liked the show too, even though I was too young lol. So I wanted to look at the dvd box art, and I saw something that made me feel uncomfortable, I saw the devil on it. I told my family I was afraid of him and didn't want to watch any episodes with him in it and asked what episodes he'd be in. The next day when I woke up, my sisters we're in my room laughing, I was wondering what was going on. I woke up, they shoved the dvd cover right and my face and yelled 'boo!'. I got scared and ran to my moms room. The next day I sat down hoping everything would be alright, I watched Goosebumps on Cartoon Network. Just when I thought things couldn't get any worse, a commercial for the game Operation, the rescue kit edition, came on and I got scared. Please not that I've had the simpsons edition of this game very shortly and saw the commercial for this game before the situation I'm about to mention happened, I didn't really mind, I was just slightly scared and slowly walked out of the room. Anyway, when this commercial played, my sisters (12 and 10 at the time) didn't know my phobia for this game, until I got so scared I turned off the tv. They wondered why I did it, then they thought I was afraid of it. So they turned it back on and skipped back to the commercial, just to frighten me! Lucky for me, I hit the 'Play Live TV' button on the remote I had. Not only did they scare me with that, but also the robot chicken dvd! The next day they didn't do anything. However, I was watching a show called 'The Grim Adventures of Billy and Mandy', the commercials came on, and the operation rescue kit ad came on. I ran to moms room again and they started scaring me! Every time we went to a retailer store like Target or Wal-Mart, they would go to the toy alise and try to find operation and scare me saying creepy stuff (I CAN'T BELIEVED THAT HAPPENED IN PUBLIC!). They even tried to record the commercial with dvr and I was strict about every recording and deleted it. As much as I loved Cartoon Network, I only wanted me watching channels that don't show toy or game commercials like Disney or abc. The next month it was new years and everything was just fine. I actually started to like the game but was too afraid to tell my mom I wanted it. I don't know what do you guys think, and if I bought up this situation to my family, what would happen? I sure hope they have forgotten this because I like this game now but I only play it at friends house.
