Scary dreams especially when I go to sleep around post 12 am

Recently started sleeping late at night as I'm preparing for my exams , one thing which Im currently noticing is that earlier when I went to bed around 11 or 11.30 pm either i used to get dreams or I don't remember any , even if I remembered there were no scary dreams , from past 1 week I went to bed around 12 /12.30 ish , man I'm like ik it's a dream but then its like 50 : 50 I feel scared i remember I'm half awake sometimes screaming in dreams .

So I have decided to follow my usual sleep schedule 11/11.30ish

Do share if any of u guys experienced such instances , also any remidies if u have

Tnx :)
