Strange flats!

I've had two very strange, but similar flats recently and i thought i'd see if anyone could shed any light on them or if anyone has experienced a similar thing?
One was a couple of weeks ago, when my bike was in the house, just resting in a room. I hadn't used it for a day or two and there are no problems I can remember on the most recent ride I did. For some reason, the rear wheel just went flat. It wasn't a slow puncture (I don't think!) because I remember squeezing the tyre lightly to check the pressures about two hours before I noticed it was flat, and the most recent ride wasn't for a day or two like I said.
Similarly, this morning, I went to get my bike from the garage and the rear was flat?! I haven't used it in 4 days, and the last ride was an uneventful 60 miler, on which I had no problems, and the tyre pressures were fine when I got back!?
Any idea what might be causing this? It just seems a little strange to me - I don't think it's slow punctures, and both have been in different places on the wheel/inner tube (Plus i've checked the wheel and tyres for possible causes!).
The pressures are all correct and have been fine when I'm riding. Just a little curious as to what it could be? I thought the heat, because it was warm on both days, but I've never heard of anything like this!
Any info would be great!! Thanks!

    If they're properly flat then I'd suspect somebody is yanking your chain. :?

    Just take the tube out, inflate it and check it under water for leaks.
    If you have no issues here I suspect it is what is said above.

    Sorted it! (I think!!!)
    Went out for a ride this morning, and had no problems, but as I was putting the bike away, I notice a small hole in the actual tyre, where the inner tube was poking through slightly! THe hole was too small to be noticeable when I just inspected the tyre off the wheel, but with the inner tube on and under pressure, the hole in the tyre opened up!
    I guess this made the inner tube much more vulnerable to punctures, even if the bike wasn't being used and perhapds got knocked or something!
    Thanks for the other suggestions anyway
