I know my life is filled with anxiety whilst my long term health issues mean I am constantly taking a mixture of medication.
Whilst I too suffer from very unpleasant vivid night mares.
This is almost on a regular basis and of course very disruptive of a good night`s sleep.
I find in the mornings that the whole dream usually bears too closely to matters going on in my life, and I feel shattered,totally spent.
Have even had vivid hallucinations...... though this can be linked to specific drugs administered in a Hospital setting.
It is extremely debilitating to say the least.
Although medication has been systematically changed or decreased accordingly,it is something I can never quite get real freedom from.
So even if I cannot offer advice I can certainly offer sincere sympathies and understanding by the bucketfull Wot..........and to all those whom suffer, if only now and again.
I do have and always have had a very active mind,so I guess this partly fuels these dreams..........or nightmares.......because they tend to be far from pleasant.
