By 15 minutes after midnight, many were waiting near the joint coordination centre in the middle of Sanam Luang.
After officials saw a lot of mourners waiting, they told them to move to wait in front of Wiset Chaisri Gate, leading to certain commotion.
Many of them ran carrying their things to occupy seats under tents in front of the gate.
They then fell asleep on the chairs waiting for the queue card distribution that will start at 8 am.
