That seems so real?

I just had a "lucid dream" that literally was two days in the dream world.
Everything seemed real, more realistic than any lucid dream I've had before.

I mean, everything was as it should be, I went to class but, ate lunch, went to the bathroom, hung out etc.

But I noticed I never learned anything in class those two days, it was something I already knew. I did reality checks and they all worked except for one in my third period.

I've always been interested in telekinesis and thought I was awake (First day) so I decided to instead of checking the time again (12:00) I focused on changing the time in the past. I look again and it's 11:55.

That probably was what made me suspicious. Then later I tried falling asleep in class and I kept seeing a pair of eyelids open while my eyes were closed seeing a ceiling. So I gave up because it odded me out. I tripped later that day and although I didn't feel any pain at all I had to get a band-aid.

Well the rest of the day was uneventful but I kept kind of getting distracted and had a hard time focusing.

I went to bed and tried doing a WILD but nothing, no tingling sensation vibrations voices or anything.

2 hours later I gave up and fell asleep normally.

I woke up the next day (False awakening) took a shower, ate breakfast and went to class. We started the poetry unit. Second period hits and I notice. The world is flat, my depth perception is gone.

That freaks me out for a bit, then lunch comes by and when I reach for my money it's all gone. I then find a 20$ bill under my foot and buy a pretty decent meal.

3rd period hits, and we jump right into WW2 from the French revolution (I always looked forward to WW2) and she wouldn't give me an explanation.

4th period and it's all SSR and I pull out a book I've read before, Eldest.

I hang out with friends the day goes by and the more time passes by the less real the world feels, everytime I close my eyes I see the outline of my bedroom, the breeze is there but I stop feeling anything I get freaked out by this detached feeling and decide to take a 1 hour nap.

I try to do another WILD and again get absolutely nothing. So I try to see where those barely open eyelids take me and focus on opening them. Eventually they open and I see my alarm clock saying "5:53 AM." in fuzzy lettering.

I focus on that then I start getting a tingling sensation and a blasting headache, my whole body goes numb and cold somehow at the same time.

Then I find myself sitting in my bed paralyzed, it's 5:55 AM and I'm creeped out thinking it was a dream, but it seemed more real than life a second ago.

I finally move, look at my computer clock and notice it's two days in the past. Today not much was like my dream but I did find a 5 on the ground in passing period.

However that whole time I had that sense, that life was unreal. That I was dreaming.

If that happens again how should I get out? How can I be certain I'm dreaming and what would a safe way to wake up be?

I know if all else fails I can do something that mortally wounds me but what if that doesn't wake me up? What if I thought I was dreaming but it was reality...

I'm really confused guys, anyone care to lend me your two cents?
