Strange feelings but only when I feel tired and try to get a little nap in late afternoon?

[Mike-tyson]

I get strange feeling in my head when trying to get a little sleep in the afternoon. But not when I go to bed at night? I am taking Amiodarone and Bisoprolol for A/F until I can get second Ablation when things settle down at Hospitals. Both medication give me sleep disturbance and day time tiredness problems. so have been advised by cardiology to try Valarian Root and Passion flower tablets to help me sleep better. And normally these work well. But wondered if they could me giving me anxiety problems when I try to have a little sleep in my chair when tired in the afternoon? I see pictures in my head of where I used to work years ago and the people I used to work with?
