"Dreaming"

When I woke up this morning I was surprised to find myself dressed. Yes. Dressed. I was not wearing the cozy pajamas I had put on before climbing into my bed. Not anymore. I was wearing an entire outfit (layers of shirts, bra, socks, jeans and all). I had set out my clothes the night before (because I had to make sure I had clean ones...not because I am crazy) and when I woke up I was wearing them. The problem is that I don't actually remember getting dressed.
As the day progressed I began to slowly remember fragments of a "dream" I had last night. I remember "dreaming" that I was afraid that there would be some sort of catastrophe, like a fire or an earthquake or something, while I slept. (You know the kind of thing where you run outside in whatever you are wearing and you're screaming, and all your random neighbors are doing the same thing.) And so in my "dream" I put on some clothes so I would bot be embarrassed about running outside in the early hours of the morning in only my pajamas.
This is kinda creepy. But even creepier is that this is not the first weird experience like this in recent history.
About a week ago I "dreamed" that there was a giant spider on my ceiling and I was not okay with that so I jumped out of bed and screamed at someone else to "check it." (I'm not sure who I was talking to or what "checking it" was going to accomplish....) then I carefully wrapped a blanket tightly around me because, obviously, it would protect me from the giant spider. The next morning I awoke tightly tangled up in my blanket and very confused (as I usually cannot sleep if I am tucked in tightly) and while talking to Tera realized that I had actually screamed during the night (oops...sorry.)
A month or so ago I "dreamed" that a colony (or is it a school) of spiders was using my blanket , a corner of which was dangling off my bed, as a means to climb up into my bed and climb all over me (shiver of grossness). I threw the blanket, all 3 of my pillows, and another blanket (all of which I feared were spider contaminated) as far away from the bed as possible, then promptly shook out my hair over the side of the bed, you know just to make sure there weren't any stray spiders in there. At some later point I woke up uncomfortable and cold. Because my neck was bent at a strange angle with my head half hanging off the bed, and all my pillows and blankets were in a heap on the floor.
I really don't know what to make of these "episodes." Should I see a therapist... because I clearly have fear issues? Or a sleep specialist....because I clearly have sleep issues? Or maybe even a sales person at Best Buy....because clearly if I filmed my self during the sleeping hours it would be amusing to watch during the waking hours.

Help.
