okay that means you should lay off the horror movies and tell your dog to shut up...
seriously you have nothing to worry about, but if you continue thinking about it and taking it seriously, you might be facing serious mental problems, think about it as having hypochondria, if you really continue believing that all these things are 'dark' signs, then you could actually convince yourself and need mental help. Which is very silly.
No you do not need to consult a priest... be a bit realistic, I know that these things are very scary and at times you don't want to be alone...but you will only end up damaging yourself. I mean the dogs might be barking at some passing by cat, and you sit in your room shivering and sweating because you believe that there is an evil presence. Be logical, and don't be swayed by fanatical explanations.
If you hire a priest, he will most probably give you a chimerical explanation, not because he believes in it, but perhaps because he might want some MONEY for his services. Do not be fooled.
So the next time you feel afraid, or paranoid, just call a friend, or go online, or turn on the lights! There is nothing wrong with doing that, it just means that you're a sensitive and fragile person!
P.S consider watching comedies at night, to alleviate the mood! It helped me out a lot!
