Awful nightmares :(

Sarah • Married 4/7/14 little boy age 2.5years and expecting 2nd baby in April 2015 ❤️
16+1 and ever since I found out I was pregnant with baby number 2 I keep having awful nightmares and can't sleep. 
Home life is wonderful
Have my husband my little boy loving supportive family :(! 
Last night I dreamed I was bleeding and losing the baby right before I was dreaming I was having the baby all alone because my husband couldn't get there..... 
I know it's normal to have these sorts of dreams as had them last time but I didn't think they were quite this graphic and disturbing.. 
Anybody else in the same boat ?
I am so tired yet hate sleeping!
