ik lig onder de atfel door een fatale botsing
"I am lying under the table due to a fatal collision."
In more descriptive: A person is laying flat on their back underneath a wooden dining table. This has happened as a result of a severe collision which indicates potentially broken furniture and a disarrayed room around them. The collision has caused severe damage, hence the term "fatal", but there's no specific relation to vehicles or roads, so the collision possibly involves household items.
