What do you do with recurring nightmares?

Sophia I.
My dreams are, mostly, crazy and very awkward dreams. I don't have nightmares very often. But when I do, I wake up crying and desperate and feeling like if I'm choking. I'm a very calmed person, so when I wake up I snap out of it quickly, realising that it was just a dream. Luckily, most of the times when that happenes, my boyfriend is next to me so he holds me and I know everything is OK, but when he's not I just hold on tight my teddy bear haha. I react calmly to a 90% of the situations, dreams included.
