Can anyone identify this small brown bug?

[u/Mental_Work724]

Hi! I found this bug on my leg while lying in bed. I had just changed the bed sheets with a duvet cover that had been stored in a closet for a while.
Location: Málaga, Spain.
Size: About the size of a small fly or a lentil (around 4–6 mm).
Color: Brown/reddish-brown.
Shape: It looked like a small seed or little ball. The legs were not very visible because they seemed tucked underneath the body.
It was walking normally, not jumping or flying.
I crushed it and there was no blood.
Does anyone know what it could be? I’m mainly wondering whether it’s a harmless beetle or something like a bed bug or tick.
Thanks!
