Bed bug (likely)

Usually hides in mattress seams, bed frames, furniture, and cracks near sleeping areas.

Feeds on the blood of humans and other warm-blooded animals.

Flattened, wingless, and mostly active at night; hides in crevices and can survive for months between meals. The image is not detailed enough for definitive identification.

Bites can cause itchy skin reactions and infestations are difficult to eliminate; bed bugs are not known to transmit disease.
