Dream of

So in my dream I wasn't dreaming about anything in particular but it was relaxed and happy like floating around in my subconscious. Then suddenly it felt like someone had grabbed my entire body and squeezed it and made some sort of inhuman sound in my ear. At this point I startled awake and thought that someone was in my room in the middle of the night and I just froze and slowly tried to move only managing to move my hand a little bit. Then after a little while I turned over. So fricken frightened. Nothing was there but I couldn't get the feeling of something grabbing me and making such a terrifying noice in my ear. Like it was low not a growl or a groan, a noice I haven't heard before. Now I haven't really dreamt or had a nightmare since I was in primary I'm twenty one. Can you interpret this for me if you can find meaning or. Is it just a meh dream?
