Why do I have such weird dreams?

Me and my friends always talk about dreams we have and theres are always relatively normal and mine arent. Im starting to think theres something wrong with me haha.The other night i had one of the most messed up dreams ive ever had. I was with a few friends and we started doing a scavenger hunt-type thing and we were walking down the street and my friend pulls out a bunch of DC stickers, you know, the shoe company, & says whenever we find something we need to place a sticker on a street pole that the item was near, I remember placing one on a pole but i didnt find anything,and i wrote my name on it,then all of a sudden i was on a boat with everyone from my highschool senior cl and we started going over a bridge and my dad was there too and he was standing near the edge and out of nowwhere this giant man in a suit bigger than the boat starts trying to climb onto it so i told my dad to step away from the edge in case he falls in( cause in real life he never learned how to swim) cause no adult was on the boat who would jump in and save him, ( oh and by the way the whole time the giant is trying to get on the boat he is holding a microphone singing ?) but then after hee gets onto the boat my dream shifts again to where im off the boat just talking to my friend who then kisses me,(hes gay in real life) and thats all i remember from it. Idk it was a lot more detailed than that but thats all i can remember.Haha I mean, i understand that almost all dreams people have dont make sense but i mean mine DONT MAKE SENSE. Could it be something i eat everyday to make me have these orr am i stressedd or what? If anyone could help thatd be great.
