A few minutes ago I finished eating breakfast, and then noticed something very strange on the floor, a few inches in front of my feet, which I had not noticed while eating breakfast. It was a green pill, a type of medicine I take twice a day. There are two very hard-to-explain aspects of what I saw:
(1) The pill is a type of prescription medicine that I am extremely careful about using (I even record on a wall calendar every time I take the pill). I always take only one pill out of the pill bottle I keep in the bathroom, and immediately swallow the pill, recording that act by making a mark on the calendar. I never leave a pill of this type lying around on a table or a couch. So for me to see one of those pills a few inches in front of my feet (on the floor) is totally unexpected, and very, very hard-to-explain. I had not yet taken the pill this morning.
(2) I had breakfast alone on a couch, holding only a tablet device and a cereal bowl, without anything else to block my view, with a coffee table about two feet away from my knees. During the whole time I ate breakfast I should have seen the bright green pill if it had been where I found it, in a spot on the floor in front of my feet, where it was very plainly visible from the spot I had sat, the pill being about 18 inches away, right in front of me. But I only noticed the pill after finishing breakfast. The floor in the room where I ate is hardwood, and a green pill on such a floor is very easy to see.
It was rather as if at about the moment I finished breakfast the pill had been teleported to the location where I found it.
Maybe the timing at the end of breakfast had some symbolic meaning. In English "breakfast" sounds like "break fast," so a symbolic warning about some part of the body breaking fast (i.e. malfunctioning soon) might occur exactly at the end or beginning of breakfast. But I admit such thoughts are highly speculative.
Below we see what I saw when I noticed the pill. The top part of the photo is the bottom of my coffee table.

Postscript (April 21): About an hour ago (in the mid-afternoon) I went out for a walk, and after leaving the front yard of where I live, I looked back at the house where I live. I noticed the light above the front door was on. I had just locked that door, and do not remember turning the light on or seeing the light on (either when I left for my walk or when I got a package from the front door earlier that day). The light (shown below) is a strong light you cannot help notice when locking the door. Also the front gate was ajar. I always close it when leaving, to discourage dogs from entering. The house was empty, and no one else with a key was in the city, two of them being on a trip that will end tonight. I've noticed a similar effect with the front door light several previous times. The light above the door can only be turned on from the inside of the house, and the light is not one of those lights connected to a motion detector.

You might suspect someone reporting things so strange as being a user of alcohol or drugs. But I'm a lifelong teetotaler non-drinker who has never used recreational or illegal drugs. I've never even tried any form of marijuana.
There was one other spooky thing this afternoon. I went out to buy food, stopping on the way to photograph a particular set of tulips I saw on the street. As always when going to the food store I went to, I took a discount card specific to that store. When it came time to buy my food, I looked for my card, and it was missing. Upon returning back home I remembered how I had photographed the tulips, and I thought to myself: maybe my discount card had fallen out to the ground when I took out my cell phone to photograph the tulips. I walked out all the way back to the tulips, blocks away, to check this hypothesis. There was no discount card to be found where I had photographed the tulips. But very strangely I did find the plastic discount card lying on the other side of the street (a wide avenue). There was no strong wind that could explain such a thing, the wind being only about 8 miles per hour.
It is possible to interpret each of these spooky events as having symbolic meaning. I have already mentioned the possible symbolism of something spooky at the exact end of breakfast. A light above me turning on mysteriously may symbolize some spiritual illumination that lies ahead. The open gate may symbolize the opening of a previously closed pathway. But what about the very strange event involving the discount card? Involving strangely finding the card on the other side of the street, this might be some symbolism suggesting the Other Side of an afterlife. A previous spooky event seemed to have Other Side symbolism.
Below are the tulips I photographed:

Post-postscript: There were several additional events involving the unexpected sighting of rubber bands, but I won't give exact details.
