I ordered some college books but got this instead. I'm wondering if this was an honest mistake or if I should be worried.

The card was sent from Moonpig. We've looked at their website, and they state that they can’t disclose the details of the sender of a card. Should he contact the police? Not as an emergency, but just to inform them. He’s recently broken up with his girlfriend, and from what I gather, she seemed a little crazy. Does anybody have any advice, please?

I received this in the mail a few days after Valentine's Day. It was addressed to me with no return address. The lid was sealed shut, and although I probably shouldn't have, I pried it open with a butter knife (I hope I'm not cursed), and a wooden box with an anatomically correct wooden heart was inside. You can buy similar things on Etsy and other online stores. Do I have an admirer with really poor taste, or is this something more sinister?

We received this in the mail today with a note from the USPS. It says, "The carrier who services your route was involved in an industrial or motor vehicle incident. Due to the incident, your mail came into contact with blood."

"He sees you when you're sleeping; he knows when you're awake."

"Ellen,
We'll be by around 7 PM on March 23 to pick up you and yours; pack light and leave your earthly husk behind. As ever, no fornicators or immigrants need to apply. I see you at 7 PM (1900 hrs).
U KNOW WHO"

I received this in the mail today. A burned sage stick, a baby doll, and an old photograph of an elderly woman. No return address, and no friends or family owning up to sending it. Just a weird prank? I'm so confused.

Update: While I was on my way home from work, my partner called me and told me that our downstairs neighbor was screaming about how we poisoned his dog, had been putting cameras in his place, and had been mind-controlling him. He then shouted at her while I was on the phone about how he wanted his keys back. So, I guess they were keys to his house? Also, he's totally insane, and I'm really glad we are moving next month.

I opened my mailbox to find this weird and completely terrifying note. It definitely seems like the person writing this was writing with their other hand to not get recognized, and this is what scares me so much. I don't know anyone who could do this, and I haven't noticed anything strange recently. I did call my close friends, and they all advised me to go to the police, which I'm planning on doing as soon as I can, but I'm not sure what they can do. One thing for sure is that I'm not sleeping tonight. Do you think I'm overreacting?

She has no idea who sent them. There is no note inside with any information on why it was sent. Her social media name was used, not her legal name.

I have asked everyone I know. Anyone I can think of would admit to it as a joke for laughs. Possibly the strangest thing to put in my mailbox.

All I have is that my dad lives out of town, where all the neighbors know each other, and he visits most of them regularly. He found most of the papers in his mailbox, and there were two in his neighbor's mailbox from across the road. They weren't in an envelope; they were simply dumped in the mailboxes.

I got this package yesterday from my apartment's Amazon Hub and I had no idea what it was because I hadn't ordered anything. To my surprise, it's a pack of seeds with a gift note from someone named K. I have no idea who this person is or how they got my full name and address, but here we are.

I'm looking for reasons why someone would send this to someone. It was addressed to me (I have only been at this house for 10 months). I live in the Midwest and don't know anyone in Pennsylvania.

Me and my boyfriend just moved to the new apartment last year. I haven’t been on any social media outlets or have disclosed my address to anyone but close family and friends. I have three bunnies, and would consider myself a bunny mom. One day, I received this random package addressed to me at my front door. I checked with all of my family members and friends, and none of them have sent this package. I don’t surround myself with people who would even send packages that are super unorthodox like this. I called Amazon about it, and they said the sender left a note saying "From Santa." I’m off-put by this. My boyfriend thinks this is from a secret admirer. Any suggestions? Should I be worried?

The only thing I can think of is that someone tried to dispose of a burner phone used for suspicious activities, but still, it's so strange. The delivery guy just buzzed the doorbell and practically zipped down the stairs, because when I opened it, he was gone.
