Salaam,
I didn't read your dream but I heard it scared you.
"I heard the Prophet saying, "A good dream is from Allah, and a bad dream is from Satan. So if anyone of you sees (in a dream) something he dislikes, when he gets up he should blow thrice (on his left side) and seek refuge
with Allah from its evil for then it will not harm him." "
[Sahih Al-Bukhari Hadith, Volume 7, Number 643]
I have also heard, though I don't have an authority for this, that to feel fear in a dream is actually a good thing.
wAllahu A'lam
