It's the dark night of the mind.
It might start after an initial awakening experience because you might suddenly become aware of how much negativity you are actually still carrying around and how confined your mind still is.
And you don't yet have knowledge/experience/trust that you can progress quickly on the path, in healing yourself, so your whole situation could seem dreadful. You then might be tempted in to trying to give up, so any idea of being victim of some sort of cosmic happening called 'the dark night of the soul' seems very appealing, but it's false, the soul is forever in peace.
