Is this grammatically correct? What does it mean? Any possible rephrasing? It be was a nightmare😂 did you have same experience?

The sentence is not grammatically correct. A corrected version could be: "It was a nightmare 😂. Did you have the same experience?" Meaning: The speaker is expressing that they found something to be very unpleasant or challenging (referred to as a "nightmare") and is asking if the listener had a similar experience. Possible rephrasing: - "That was a nightmare 😂. Did you experience something similar?" - "It felt like a nightmare 😂. Did you go through the same thing?"
