Am I perchance cooked

So I was at a friends house, staying from Saturday-Sunday and it was late in the night, we just downed a pizza and we were dying of heartburn and such so we were just laying down watching yt. My friend has weird sleep patterns so around 12 he passes out, I stay up and watch YouTube until about 12:55 we’ll say. I go up to blow my nose before I head to bed, I turn off the lights, get under the covers, and check my phone to see I’m getting a call from someone with “no caller id”. I pick up the phone to see who it is and I hear a kind of whispered voice that says, “I know you wear glasses everyday.” I immediately think this is some joke so I say “do I?” (I do) they respond with “I know you wear glasses and a hoodie everyday.” I think this is a little creepy cause I do. I live in two separate towns though so I can imagine it’s someone in the town I live in primarily and I go to school in just trying to play a prank on me. I hear the person, who I can’t tell who they are by their voice, start laughing and I hear some other person laugh with them. So at this point I’m almost 100% sure that it’s just something to mess with me. After the laughing persists for about 5 seconds they hang up. I try to brush it off until about 3-4 minutes later I get called again. Someone again with “no caller id”. I assume it’s the same person so I just say “what do you want dude” as soon as I answer. They respond with “I know who you are, I really like you. I’m outside your house in (other town)” at this point I’m freaked the hell out, I don’t tell much people that I live in two towns other than close friends and administrators at my school. At this point my friend woke up and overheard the call. He walks downstairs immediately and checks the doors. Immediately he runs back up and says “hang up right now, I’m not joking.” We checked the whole house and nobody was in there or anything, but the back door ended up being unlocked from much earlier. Thank god we were safe. I was at my friends house at the time and my dad has a gun so I knew he’d be safe but I contacted him to make sure. Still that was creepy. I didn’t end up going to school today because 1, I’m sick or something and 2, I’m just scared because the person also said in the call “I’m gonna f** you” a couple times. I’m pretty sure this was a girl but I have no clue, again, I couldn’t really tell by the voice but I’m still scared and I’m almost positive I have to go to school tomorrow. What do I do?

TLDR: I got some call from someone who said they were outside my house in another town and they were gonna r** me, help please
