Cats and Dogs see Ghost?

I have 2 cats and a dog, and when my grandma passed on they started whimpering and meowing. I never found out until the next day that she had passed on...

we have about 2 adult cats, 2 adolescent cats and 8 kittens and 2 dogs plus other dogs in the neighborhood.i don't know why but i hardly could sleep past 11 pm. and when i get to go to sleep it annoys me so much because the cats would randomly climb on the couch (i sleep on the couch in the living room, i have no room) and step on my face then walk towards my abdomen then lay there apparently looking at something in the dark. it's eerie sometimes just like the night before. and everyday at 3 am when i'm still awake, i managed to hear the dogs barking at something or fighting something and after that something would be jumping off the roofs and the dogs would be barking at its trail. i'm just hoping that they weren't seeing things

usually our dogs would bark or howl at our basement... and i feel kinda creepy when they bark or howl at the darkness or at full moon...

I reckon they can sometimes my cat use to look just up at the roof and stare i was pretty confused and this was some years ago as ive moved alot of houses *but just around the same town* and ive had this cat since i was about 7 and she/he was an adult it was someone elses cat but came to live with us instead dont know why ha ha and im now 19 and shes still alive today so shes pretty old in the house i am right now she was looking up at the roof again but i think it was because of the air con but..he's/she's never done it again or before that time i think also he/she likes to think its a dog but thats another story ha ha

At the minute I have two dogs and before them I had one.
My first dog would always open the bed room door and stand infront of my bed growling at the large mirror on the opposite wall however it could always have been growling at it's reflection but I think not as you know what they say about mirrors.

My two current dogs often bark when I take them out for a walk of a night. The strange thing is I always feel like I'm being followed by something in the trees. Dogs and cats are both known to see things and smell things. They have better senses than humans and can pick up on certein frequences and electric feilds that we can not.

Hmm... Perhaps they do.
In Philippines, the dog started barking at something in the darkness. This was during my stay with my relatives living at the base of some heavily forested mountains. Thank God it was just a few minutes to New Year. Cos' the noise that started must have scared whatever it was off. The dog stopped barking after the fireworks and celebrative shouting.

i do own a cat for more than 10 years.
A Black cat.
Sometimes, my cat will make lots of noise at night in the living room when everyone asleep, but it's sounds different, not the meow2 type! Lolz
It sounds like Auuuwww, Aaauuwww.
So what you all think?
Usually my cat will face to the kitchen.

I remember reading that when a dog barks it has seen a devil/demon of some sort. Usually late at night my cats start climbing on the screen door to be let in. I dont know if they just want company, even though there are three of them, or are afraid of something.
