Dream sign...maybe

Hiya, i'm new to this site and dream-recall, dream-signs etc, but I think I might have figured out one of my dream signs, but i'm not sure.

In the past 3 dreams I can remember (been over the past 3 days), they have all included computers. I'll give you a quick overview of the dreams:

1) The sky became very dark, and I had to get home. I got on a bus, and when I got home I found my mum on my computer.

2) I was in a school, and I was stealing things from a vending machine with my friend. Suddenly a thing called a "Slam Alarm" went off, and police stormed the building. Me and my friend decided to keep stealing stuff :eek:
We got dragged down to a Central Operating room filled with computers and got interrogated.

3) I was in an I.T department of an office. I saw a UFO outside but it turned out to be a cardboard cut-out dangling from a piece of string.

The thing is, I spend alot of my waking time of computers as well- so i'm not sure whether this is a dream sign or just a reflection of my real life :?

Any guidance appreciated, cheers :)

Dream signs will often be things that also appear often in our waking life, as we tend to have dreams related to to our waking lives. It sounds like computers is a dream sign for you, though you should record more dreams before deciding. You can treat it as a dream sign if you want to, though. :D
