Over the years I have had many random ghostly occurrences, But what happened with my alarm clock has to be one of the strangest.
I have a digital alarm clock/radio A few years back I removed the back up battery because it had gone dead. Since then the clock has worked fine while plugged in.
Until a couple weeks ago. When all of sudden at 3:21 pm the clock alarm went off for 1 beep then it stopped, then it went off for about a half a minute until I got up to go shut it off. It stopped when I got about a foot away from it, then it went to the alarm set screen for about 20 second then back to clock.
Normally the alarm going off wouldn't be strange except that this clock has 2 alarms neither were set and even if they were set the last times they were set for was 5 pm and 11 am, So there was no reason for it to go off at 3:21.
The other weirdness about it is the clock going to the alarm set screen you have to press and hold the alarm set button for about 10 seconds to get it to that screen and when the alarm is set and goes off it goes off for 1 hour before shutting off not only about 30 seconds.
So I went upstairs to tell my dad about it because we have had some ghostly experiences before in our house and in truth I was bit freaked out so I stayed up there for about 5 minutes
When I finally got the courage to go downstairs again I checked the clock and it was on the normal time screen. But as soon as I started watching the clock it went again to the alarm set screen again and then back to normal time.
So I watched the clock for about 10 minutes nothing was happening. Finally I said "if your still here make it go back to the alarm set screen" and within 30 seconds it went back to the alarm set screen. I have asked a few times since then but since then it hasn't done anything unusual.
At first I thought well maybe my clock is starting to go out but seeing as this has not ever happened before this and hasn't happened since then it seems like it could be a spirit and the time chosen of 3:21 is my mom's birth-date and she recently died in August. So I am hoping it is my mom's spirit coming and visiting me. My mom believed in spirits and we were talking about it one day long before she passed away. I told her if you ever can contact me from the other side use the electronics because knocking things over in a house this chaotic would go unnoticed. Looks like she might have remembered.
