Am I being unreasonable?

I live with my mum, my dad and my lodger. During the cold days and nights we had people round here every week, I didn't mind as it wasn't like everyday. But now it's sunny and the pool is up lots of people are constantly round 24/7 and I wouldn't mind but most of them just turn up without seeing if it's okay first. Most the people that come round i personally don't like but they still come over anyways and most of them ignore me so I go and sit in my room because its so boring. I don't mind people coming over its just everyday from early in the morning till late at night drinking lots of alochol and making loads of noise and leaving the back gate open (my mums dog runs off) and throwing me in the pool after knowing how I feel about it. I have spoken to my mum about it but she gets really mad at me and does this whole, "They all care about you, life is too short to be stuck in your bedroom." speech and it's getting me really mad. Am I being unreasonable by wanting the odd day with just my family or having my friends round without lots of grownups talking about sex and getting drunk. Im 15 btw.Your opinions please.
