I barely make threads, but in honor of Halloween I thought I'd create one. This question has been on my mind for a couple of weeks ever since I saw @patrickklepek mention his fear of alien abductions (or just home invasions in general) on Spookin' with Scoops.
What would frighten you more? Let me break down the scenarios for you.
Alien Abduction: You're home alone, your family/friends/roommates decided to go out that night to have fun. You, on the other hand are slightly ill and can't go with them. You decided to stay home, rest and maybe take some medicine. It's 11 p.m., you're on the bed, watching T.V when the power goes out. All of a sudden you see lights shining from your window and out of nowhere you see 3 aliens staring at you.
Stranded in the water with a sea creature circling you: You and your friends/family are out on a boat, enjoying your day. The boat hits a bit of a wave while the boat is in motion which sends you overboard. Your friends notice immediately and tells the person who's piloting the boat and he begins to turn around to get to you. But, since they were going reasonably fast they have to slow down to make sure they don't pass you.
While in the water you feel a bump. You turn to look, thinking it's a shark; no dorsal fin, nothing. You feel another bump on your left side so you turn to see what's been bumping you. Expecting it to be a shark you prepare yourself when you come face to face with a creature you've never seen before. It's circling you, staring at you. You see it's slitted reptilian eyes locked onto you. The boat is still a couple hundred feet away, so it's just you and that creature.
