Hello @Egbohills
Welcome to our community and thank you for your question.
It's possible to apply for asylum again in the same country. In Germany it's called "Asylfolgeantrag". You can apply this way if the situation in your home country has changed for the worse since your last application.
Since you left Germany in the meantime you will have to live in a "Erstaufnahmeeinrichtung" again (for a maximum of 6 months).
Best regards,
Thorgen
