When you're laying in bed, the bed applies normal force solely due to gravity acceleration
the normal force of the bed is (Your body mass) * (Gravity acceleration) upwards, which cancels out the downward force of gravity which is (Your body mass) * (Gravity acceleration) downwards
Hence it can be argued that gravity is pulling you down while also pushing you up such as that you stay at the exact same place
