Toddler fears

This is in regards to my almost 2 year old daughter not my pregnancy but I'm looking to see if this us common. She is very attached to her daddy and I. I breastfed her the first 14 months and have been a stay at home college mom so she always always has me around. We recently moved into a home we bought and she's done wonderful with the changes. At the old house she slept in her crib, in our room. Now she sleeps in her crib in her own room right next to us. Most nights we go in to out her down give love and she'll tell us ni night and goes straight to sleep no crying or anything. But occasionally she acts completely mortified to go to her room for bed.. Like screams hysterically, alligator tears, almost hyperventilating.... What the heck?? She's had night terrors since about 8 months and when she has them we go get her right away and she'll come to our bed until she's back too sleep and comfortable... I don't know what to do for her. She freaked out again tonight and is rocking in the chair with daddy... anyone else deal with this??

Sidenote I am 28 weeks with our baby boy and she has been involved in the pregnancy since the beginning and is very excited about " mommy's baby". She goes to the Dr appts with me, helped me hang his clothes, puts lotion on my belly and gives him hugs and kisses all day... We don't leave her out of anything she is the center of our world.
