The last few times in which I have woken up from a nightmare have involved dogs. I haven't had a nightmare that still had my panicked when I woke up in a long time but the last one I had involved a doberman/Rottweiler type of dog.

I have no fear of dogs at all, I love dogs(not as much as cats, but still) And I have a soft spot for the great big ones such as German Shepards, huskies, Akitas, wolf-dogs etc. I don't have any memory of being afraid of dogs either.

So i think it's strange that the only nightmares that I wake up from involve one or more dogs. After such nightmares I usually can't fall back asleep for a night or two. Is this normal at all? Is there any meaning to it?
