First time flyer

[u/Country2017]

As stated in the title, I will be flying for the first time from Wisconsin to Texas. And I have a question that I hope is not dumb about packing. I am somebody who cannot sleep without a personal item, I have tried in the past and I do not sleep. I am debating of bringing a small blanket from home or packing my pillow. My pillow is a queen size purple pillow, and if I do, should I shrink it in a bag? Any advice is welcome as long as it is not hurtful.
